Get Back in Line!

As the end of December approaches and we get into the depths of winter (California winter, of course), we are busy with our planting projects in the gardens.

 

High on the ‘to-do’ list was to replant a terraced garden in Officers’ Row, the eastern facing gardens. These gardens were first rehabilitated in 2006 and looked fantastic for the first 8 years, but had noticeably declined this past summer. This garden is open every Wednesday for our casual garden viewing with a gardener present so it was vital that our showcase garden impressed our visitors.

 

The gardens were designed by the late Carola Ashford, the first project manager, to resemble the cutting flower gardens created by the wives of the federal penitentiary during the 1940s and 1950s. She selected perennials and bulbs that would give year-round color based on a few key photographs.

In the photos, reds and yellows are predominant, so Gaillardia ‘Burgandy’ and ‘Goblin’ were selected to give the cheerful look. Yellow Aurinia saxatilis, gold basket, was chosen to edge the pathway mixed in with blue Muscari, grape hyacinth, for a spring mix. Heirloom daffodils were planted in rows to bloom successively through the spring months. As the garden matured, many of the neat planting rows were beginning to meander, and the perennials were not blooming as fiercely as they once had.

 

While we could have gone back to Carola’s original planting plan and done the same, this was an opportunity to introduce a few new plants to Alcatraz that provided the look we were after.

 

The first step was to supplement the soil with rich compost from our own pile and chicken manure that we had purchased. The sparrows had a field day scurrying around after insects.

The burgundy gaillardia was replaced with Coreopsis tinctoria ‘Tiger Stripes’ that has a brilliant mix of red and yellow on each flower. This is a very forgiving perennial that also makes a great cut flower, plus it is also an heirloom plant, first introduced in 1885. We did keep the Gaillardia ‘Goblin’ but needed to transplant a few of the plants to keep the orderly lines of cut flowers.

 

We have become big fans of Coreopsis!

We also introduced Coreopsis grandiflora ‘Sunburst’. This is a great bloomer with golden flowers. The coreopsis does perform better when regularly deadheaded but this garden task is very meditative.

 

We had also noted that the garden was lacking in fall blooms – we would always make an emergency trip to the local nursery for some fall plants to fill in the blanks when the iris and dahlias had died back. This past fall we purchased Rudbeckia, black eyed Susan, to give us the extra color we needed, and they were very happy on the island. So happy that they spread! Not a lot, but they were wandering. We never had the heart to weed out the strays, and the neat lines of a cutting garden were beginning to be lost.

 

The bearded iris also needed rethinking. This was a difficult one, as they are legacy plants to the gardens. Mostly blooming in spring, the large section of iris would remain barren and become a chore to nip the brown leaf tips throughout the rest of the year. We dug up the entire patch (and hopefully got rid of some nasty grass with long rhizomes as well) and tucked a single row of iris between the gaillardia and the coreopsis. The iris blooms should rise above its neighbors and then we can cut the foliage back to be hidden by the other perennials.

We also added in a few missing plants – a couple of Limonium perezii (statice), penstemon (beard tongue), and centranthus (Jupiter’s Beard). With Centranthus being a notable naturalizer, I refused to buy one. Ironically, we had to hunt around for a seedling of a red centranthus, the gardeners do a great job of removing them.

 

The daffodils remain to be tackled though. This will need to be done in the spring when we can identify each flower. The dahlias and the daffodils are inter-planted as they bloom at different times of the year. Unfortunately, with constant digging in this bed, the neat rows of heirloom daffodils have become interspersed with each other. The daffodils will need dividing anyway, as they have formed big clumps that are forcing themselves out of the ground.

All in all, it was a great week to be in the gardens. Now we just need some rain.

Mallow Versus Hollyhock

 

Two similar plants that often get confused are mallow (Lavatera) and hollyhock (Alcea). A quick glance at these two and it is easy to see how they can be mistaken for each other.

 

Both plants belong to the same family of Malvaceae, and so they do share many common characteristics. The flower is the most obvious similarity. Resembling a hibiscus flower, the lavatera is very showy in shades of

pink, red and white. The flower of the hollyhock is also very pretty and in similar shades. Both plants can be annuals, biennials or perennials, although the Lavatera is more often seen as a shrub in gardens while the hollyhock is typically a biennial with a stalk of flowers during its second year.

 

The hollyhock, with its 60 species, is native to Asia and Europe while the Lavatera, with 25 species, is more of a world traveler.  Its range is in the Mediterranean region, central and eastern Asia, Australia and from California to Mexico. Looking at the adaptability of the Lavatera, its no surprise that it can tolerate a wide range of soil to grow in. It actually prefers sandy, rocky or even clay soil in coastal regions (perfect for Alcatraz!). The hollyhock is a bit more fussy preferring rich, well drained garden soil.

 

On Alcatraz, we have introduced the mallow,

Lavatera assurgentiflora. Native to the Channel Islands, it has naturalized to the coastal areas of Southern California. We have had it in our Prisoner Gardens on the west side of the island for over a year now and it is doing extremely well. The shrubs have grown to 4 feet tall and wide, and have been consistently blooming for most of the summer and is still going strong.

Most of our hollyhocks have set seed already and we will have to replant them again next spring.

 

Both hollyhocks and mallows are good for hummingbird and butterflies.

 

We often tell visitors the common name of the Lavatera is mallow, which then leads to them asking if this is where marshmallows come from? The answer is ‘no’, marshmallows were originally derived from the plant Althaea officinalis, native to Egypt, but it is a member of the Malvaceae family.

 

Both Lavatera and hollyhock fit nicely with the cottage garden style of the Prisoner gardens with our mid1940s time period and we are already looking at seed catalogues for next year to add more to our gardens.

Plants from Around the World

As visitors arrive on Alcatraz, they are greeted by a Park Service ranger who gives them an orientation to the island. The ranger needs to keep the crowd entertained until the entire boat is empty before they can dispense the vital information of where to get the audio tour and a few words of safety.

 

Each ranger shares different snippets of the island’s history, little teasers to keep people occupied. Having listened to the ‘dock talks’ for more than 6 years now, I’ve heard most of them and to be honest, it’s where I’ve learned most of the more interesting pieces of Alcatraz history.

 

One of my favorite talks is a true or false quiz. The ranger makes a statement, and then gets people to raise their hands if they think it is true or not. One of the questions is ‘True or False – Alcatraz hosts plants from every continent except Antarctica’. There is usually a split amongst the crowd of those that believe it is true, and those that doubt the statement. But, the answer is TRUE!

 

Even before we began to introduce plants

to restore the gardens, the plant survey done in 2005 found that there were more than 200 species of plants still surviving on Alcatraz from the gardening days of the military and the federal prison.

 

 

 

 

 

The range in plants from the different continents is quite surprising – how could plants that are from drastically different parts of the world all survive on a tiny 22 acre island?

 

 

 

This is one of the aspects of the story of gardens that I love – these surviving plants, introduced years ago, could survive on their own because they each found the right microclimate on Alcatraz to make it.

 

 

 

 

Here is a partial list of the surviving plants by continents:

 

North America –  Monterrey cypress, Agave americana, Douglas iris, various ferns

 

South America – Nasturtium, Fuchsia

Not only do we have plants from around the world, but we also have visitors from around the world. Again, with the exception of Antarctica.

Sharing Gardens

Gardeners tend to be sharers, whether it be gardening advice, seeds, surplus zucchini or to just share their gardens with others. The inmate island gardeners were no different. They shared flowers with island residents on Sundays by leaving bouquets at the dock, and they traded seeds and gardening advice back and forth amongst themselves. However, one thing that was not permitted on Alcatraz was to visit each other’s gardens.

 

Inmates Elliot Michener, who gardened the West side Prisoner gardens, and his friend, Richard Franseen, who tended the Rose Terrace on the East side of the island, were not allowed to visit each other’s gardens. With five overlapping years of served time on the small island, the priviledge of enjoying their friend’s garden was withheld – another small reminder to the men that they were still in prison.

 

Gardeners from around the world now visit the island to see the restored gardens. On behalf of Elliot and Richard, it is our pleasure to share the gardens with them.

 

On the reverse side, it is also fun to go and visit gardens and be lucky enough to get the ‘special tour’. The horticulture world is pretty small, whether it is the Bay Area, USA or even worldwide, chances are there is a connection that will add a spark to your trip.

 

I was lucky enough to have Marion Brenner ask me if I could show a couple of her friends from France the gardens while they visited San Francisco. Marion is a longtime friend of the Garden Conservancy and professional photographer and landscape designer. Her work has illustrated many articles in garden magazines and publications, including Martha Stewart Living. Delighted to be asked, I mentioned that I actually had a trip planned to France. Marion quickly put me in touch with her friend, Catherine Delvaux, editor of the bi-monthly garden magazine Detente jardin, who had been showing Marion around Paris for her upcoming book on Parisian gardens.

 

Catherine generously offered to pick us

up in Paris and drive us to Monet’s Giverny garden – a garden high on my ‘must see list’ While Catherine knew the head gardener, he was pretty busy and we never had a chance to meet. We learned that upon undertaking his position, he had researched which heirloom varieties were available during Monet’s time and has since recreated overflowing beds of color. Monet grouped plants by color so he could study the effect of the lighting on them. In fact, he chose to make Giverny his home because of the quality of light in the valley. Seeing the ‘real life’ version of the lily pond was quite impressive.

Before leaving the tiny village of Giverny, Catherine took us for quick respite from the warm day in a shaded restaurant courtyard just down the street. The restaurant actually had an entire hillside garden behind it that had the starting signs of being neglected and on its way to being overgrown. The little garden had its own charm and not a single person in it, despite the busloads of visitors just down the street.

 

Catherine next took us to an out of the way garden treasure by the name of Le Jardin Plume. This country garden is also not as popular as the famous Giverny, but it should be. A couple had bought three hectacres of farmland in 1996 and have slowly turned it into many garden rooms separated by shaped boxwood hedges.

Each room is a surprise – we wandered through butterfly gardens, prairie grasses grown in quadrants, and each room offered unique plant combinations. We were able to meet with the owners and I really wished I had paid more attention in my grammar school French classes, but we managed to have a full conversation. Even in French, the word Alcatraz needs no translation.

Being a tourist instead of being a staff member at a famous destination was an eye opener. It is really too easy when we are at work to just focus on getting the tasks done, but on my trip, I’ll always remember the staff that took the extra time to chat or to point out something, or even to just help with directions. So, please, ask the staff and garden volunteers questions! We do love to help and more importantly, we really want to share our gardens with you.

It’s a Girl!

Alcatraz garden volunteers have faithfully been monitoring selected native plants on the island since February as part of the California Phenology Project.

The native plants have been scrutinized at least twice a week for growth of leaves, flower buds, open flowers, pollen release, fruits, ripe fruits and seed/fruit drop. For each of these observations, a quantitative estimate is given. Among the native plants that have been closely watched is Coyote brush, Baccharis pilularis.

Plants are fascinating to grow for whatever reasons the gardener finds rewarding – the promise of food, the enjoyment of the flowers, providing habitat, or just for the fun of it. For the phenology watchers, learning each plant secrets has its own rewards that only come after months of observing. The four coyote brush on the island have finally revealed the secret of their sex to us! Alcatraz has two males and two female plants.

Everyone knows that (most) plants have flowers, but many people may not realize that the flowers have male and female parts, and in some cases, that the male and female flowers are on separate plants.

The coyote brush is one of the plants that have the male and female flowers on separate plants. This is known as being dioecious, meaning to have two houses in Greek. The opposite is to have the reproductive parts on one plant, or in one house, being monoecious. What is the difference between the male and female flowers? The male flowers contain the pollen, held on the anthers, while the female flowers open to reveal the stigma and

style. Bees or other insects will take pollen from the male and will brush the pollen on the female flowers in their effort to gather nectar. The female flowers are oblong with a narrow opening at the top. Inside, the pollen will land on the stigma and ‘travel’ down the style to the reach the ovary where the seeds will ripen. Once the seeds are ripe, the seeds will be dispersed by the wind carrying the fluffy tufts away. On Alcatraz, there is a lot of wind, so the seeds are dispersed quickly. 

The first male plant began to flower on July 17 and finished flowering September 25.The females flowered next, while the second male plant began to flower September 25 and is still flowering. It is interesting to note that the

male plants are growing on different sides of the island, and have different flowering times. Maybe after a few years of observations, we can draw more conclusions about why this is. By flowering at different times, the cottony female ‘seeds’ are released and float on the wind to be carried away to reach a distant male. This helps to increase the genetic variation amongst a plant population – a cool evolution trick. 

Can you think of other plants that have male and female flowers on separate plants?

Here are a few – holly, gingko, kiwi vines and mulberries. Knowing which plants have separate male and female flowers will help gardeners plan their garden. For instance, if you wish for bright red holly berries, you must plant a female bush, but you will also need a male to fertilize it. Or, you should also take into consideration garden maintenance – a messy female gingko tree will drop the fruit or even the female coyote brush may be too messy for some people’s liking. 

At any rate, plants can continue to amaze, just take the time to notice them.

Way back in April…

Way back in April, our gladiolus corms arrived in the mail from Old House Gardens. We tucked the little corms into the raised bed in front of the greenhouse and have been waiting expectantly for the heirloom flowers to appear.

 

Over the past two weeks, the flower stalks have emerged from the center of the fan shaped leaves, revealing their bright blossoms a little bit each day. Even though they were all planted the same day, at the same depth, they are not all blooming at the same time, perhaps some are in more rush than others, while the others prefer to take their time.

 

It would be hard to pick a favorite flower, they are all very pretty, and I can see why this old fashioned flower continues to be popular.

the plant trade in 1908 is a small and graceful gladiolus that multiplies each year without much care. According to the growers at Old House Gardens, the corms survive in zone 5! Like many heirloom plants, this corm was collected at an old home site and lucky for us it was found, as it was named ‘Bulb of the Year’ in Spring 2008.

‘Dauntless’ is every bit its name – pink with a dramatic splash of ruby in the throat. This corm is one of the oldest traditional gladiolus offered by Old House Gardens.

on the Old House Gardens’ website as ‘exotically patterned in a style that dates back to Victorian days, this small-flowered, vibrant pink cutie is randomly flecked with deep rose’. The flower easily blends in with a Victorian garden of the military years or with the hippy flair of the 1960s.

The frosty pink Gladiolus ‘Friendship’ is listed as a ‘landmark pink that has won every prize there is for glads’. In fact, “60-some years after it first bloomed for the legendary Carl Fischer it’s still considered world-class”.

 

 

 

 

 

 

 

 

 

 

 

The flower of ‘Melodie’ was a pleasant

leave you wanting to grow more of them. This little guy was rescued from an abandoned homestead in the Appalachians near Boone, North Carolina. It has graceful blooms of soft apricot and it is hardy through zone 6 and perhaps 5 according to Old House Gardens reports.  

 

 

The Abyssinian gladiolus was documented in the 1996 book Gardens of Alcatraz as growing on the island. The plant had long disappeared when the Alcatraz Historic Gardens project began in 2003, so it was finally time to bring this graceful glad back to the island. Introduced in 1888, perhaps it was grown by some of the military wives in cutting gardens. Collected from the mountains of Ethiopia in 1844, it reached America by

1888 when it was featured as brand new in Garden and Forest magazine. Formerly Acidanthera, it is now called Gladiolus callianthus ‘Murielae’. We ordered 100 of the little corms, most are planted in one raised bed in front of the rose terrace greenhouse, it will be a great site when they are all in bloom.

 

 

 

 

 

Our rarest purchase was the

‘Lilac & Chartreuse’ gladiolus. Introduced in, 1960, it is a shame that it is not grown more. The flower is pretty eccentric, just like the 1960s themselves – ruffled and lavender with the chartreuse thrown in.

 

I hope to add more heirloom gladiolus every year and build up our collection of these wonderful old favorites, and hopefully entice visitors to grow them too.

A Garden Renovation that could not Wait

Winter is the usual time for us to do big garden renovations; with the winter rains, the absence of birds and fewer visitors, it is the ideal time to make changes in the garden beds. However, we had one garden area that just could not wait another couple of months.

 

Our little ‘chapel bed’ along the main roadway desperately needed some TLC. In the spring, this garden looks fantastic and is often the first bed where visitors stop and say ‘wow’ at the size of the Aeoniums. Most visitors are accustomed to seeing these ‘hens and chicks’ plants the size of a tennis ball, not basketballs, the size they easily grow to on the island.

The plantings in this bed were actually rescued plants from construction staging sites before the Alcatraz Historic Gardens Project began, way back in 2000. But after thirteen years, many of the plants were crowded, the rhizomes of the bearded iris were choking each other and the Aeoniums were getting very leggy (garden talk meaning, too high with the growth only at the tips of bare stems). The Aeoniums, both purple and green, do not look their best at this time of year – in response to the dry conditions in our Mediterranean climate, they drop their lower leaves and the remaining leaves shrivel in to hold onto any moisture they can.

 

The soil itself needed amending too. Each year, we have added soil to the perimeter of the bed, but could only apply topdressing, not incorporate our rich compost into the soil.

 

In a bold move, we decided it was time to clear out all the plants, saving the existing Solanum marginatum, Drosanthemum and the shrubby Hebe. Karolina and a few volunteers dug out all the plants, taking cuttings of the succulents and selecting the healthiest iris rhizomes to replant. In preparation, we had been taken cuttings of the Aeonium and were growing them in the greenhouse.

The new plants were set out in roughly the same arrangement as before. We also added in tall Verbena bonariensis to give some height and some billowy color through the summer and fall. We also removed some non-historic Gazania rigens along the front edge that always required water and planted legacy Pelargonium ‘Prince Bismarck’ and heirloom Pelargonium ‘Apricot’ that has done very well for us in west side Prisoner Gardens.

We will need to water the new plants until the winter rains begin but, this drought tolerant selections should be just fine with weekly watering until they are established.

Tough Gardening, Part 2

Nurturing plants to soften the starkness of the prison island has its challenges. The island’s past residents certainly must have realized this, but they were determined to coax blooms from the Rock.

We are following in the footsteps of those early gardens and I find myself often wondering ‘how did they do it’, and being impressed with their dedication to creating beauty in this forbiding environment.

The military landscaped the main road that leads from the dock to the top of island, where the Citadel, the military fortification, once stood. They created pocket beds and even used cannon balls to line a parapet wall in front of the commanders’ homes, known as Officers’ Row. When the military left the island in 1933, these homes would later be turned into gardens in 1942. To move away from the military look, the Federal Bureau of Prisons, removed the cannon balls and built a trough planter along the entire wall – 330 feet in length! The maximum security surely must have been taken with the gardens left behind by the military to go to these lengths.

In 2005, the trough planter was the first garden area to be restored and it was replanted with ivy leaf geraniums that would have been available to gardeners back in the 1940s. We quickly learned the challenges of gardening on the Rock, when the resident gulls pulled each plant out!

The historic trough planter being repaired in 2005.

The historic trough planter being repaired in 2005.

We have gotten smarter since then, and now have heavy guage wires to protect our precious plants. But the challenges did not stop there.

Luckily, the trough is located on the leeward side of the island, so wind does not dry out the plants. However, the trough, being made of brick and only one foot in depth and tends to dry out quickly in the hot summer sun. A drip irrigation line had been installed for weekly waterings, but then we were also reminded that water will find the easiest path to drain to – the water tended to run down the inside of the trough, before finding a drainage hole and seep away – doing little more than just wetting the sides of the trough, and not soaking the roots of the plants at all. We now alternate hand water and the drip irrigation to ensure that the plants are getting enough water. When we do use the drip irrigation, we also turn the water on for 10 minutes, then off for 20 minutes, then on again for 10 minutes to allow the water to soak into the soil instead of just running out any cracks. As a plus though, the dripping trough supports ferns, hydrangea shrubs and fuschias that are growing below the trough.

Feeding the pelargoniums is a must. We enrich the trough soil every year with our compost, however, regular fertilizing with kelp emulsion keeps the flowers blooming and the leaves green all summer.

The steady maintenance of deadheading the spent blooms is enough to keep a crew of volunteers busy. Aside from this expected maintenance, our gull friends insist of sitting on top of the wire cages (I guess this gives the best lookout).  We usually have a few broken stems each week that need to be pruned off.

Despite all this work, the gardening is a labor of love with rich rewards.

Words from the Rock – a collection of poems

Our upcoming Florilegium of watercolor paintings of island plants will also be showcasing written poetry about the gardens. The poems are a collection of ‘Compare and Compose’ Poetry that was put together by a National Park Service intern in 1992. Mary Schumacher organized  an interpretive program where visitors to the island spent a couple of hours walking the island and gaining inspiration from the landscape.

The poems have had little mention since they were written over two decades ago, but Mary has held onto the treasured poems. The gardens have changed dramatically since inspiring the writings, but the spirit of the gardens still remain – cherished plants brought to a desolate island to provide beauty, the neglect of the gardens, the determination of the  plants to hold onto the life they had.

With the poems being presented alongside the art, at long last, they will be read and provoke thought once again about the importance of plants and beauty in our every day lives.

 

 

Now the ice plant

lives on the cliffs

of another age.

In the purple light

of dawn

the flowers

are also purple.

When the rock it hangs on

begins to crumble

piece by piece

breaking to new form…

the plant cannot

remember another age.

Tough Gardening

Sometimes it is not easy to uphold our garden goal of having every visitor amazed by the beauty of the gardens and to experience high horticultural standards. We wish that each of the 1.3 million visitors to Alcatraz a year (5000 per day) be able to appreciate the gardens regardless of the time of year -– whether they see them in the lushness of spring, or the dry and windy autumn.

 

The garden restoration is now in its tenth year, and we have really come to know the difficult areas of the gardens. The obvious is the windy west side, but even this side, through trial and error (much how the inmates learned), is for the most part flourishing at all times of the year.

 

One challenging garden area remains though – the series of terraces built by the inmates in the 1940s. Facing the Golden Gate Bridge, this area is a haven for hummingbirds and sparrows in the spring with the overflowing terraces of Echium and Chasmanthe, the complementary blue and orange colors standing out against the backdrop of the cell house.

The sandy soil has received annual topdressings of our rich compost for the past 3 years, but the soil still tends to dry out and become compacted mid-summer, despite hardly anyone walking on these beds.

These terraces do hold many of the survivor plants on the island – Echium, Chasmanthe, Aeonium, Artichoke, spuria Iris, Acanthus mollis and even Rose ‘Russeliana’ – so we know that plants can grow and thrive in these soils. The trick will be to find plants that add to the existing palette to have a garden to show off all year round, instead of the plants going dormant mid-July.

 

The terraces were rehabilitated in 2009

as part of the West Side Treatment Plan. At the time, we examined historic photos to identify plants that the inmates may have been growing. The photos clearly show gladiolus neatly staked and plenty of unidentifiable low growing mounds. We replanted the top terrace that runs along the parapet wall with Pelargonium ‘Brilliant’, an island survivor. The plantings did well up until last year, when sections started to die out and we eventually removed them all. This year, we are experimenting with a purchase from Annie’s Annuals – Dicliptera suberecta ‘Uraguayan Firecracker Plant’. With deep weekly waterings, the 4” potted perennials are off to a good start.

 

Bill Noble, Director of Preservation for the Garden Conservancy, visited the gardens last month and this area was examined. Bill visits each of the preservation projects several times each year and lends his expertise and guidance to the gardens. Bill’s perspective is a valuable resource, as often, gardeners need some ‘outside’ advice. Bill suggested tying in the established plantings of succulents on the slopes above the roadway. The succulents would be an ideal choice to give a garden that has year round interest and that is drought and wind tolerant.

 

Gladiolus will likely not be making a come-back in this garden bed – we can only be impressed with the skills of the inmates to grow such beauties in this tough spot.
