Category Archives: Gardens of Alcatraz
Earth Day typically involve activities that focus on native plants and restoring habitats, but the day was also an opportunity to demonstrate that gardeners can landscape with drought tolerant non-native plants that are not invasive. Hosting a garden table with Alcatraz Cruises’ Earth Day celebration last week was a chance to highlight plants growing on Alcatraz, that while not native, are extremely well suited to the climate they have been thriving in.
From over 200 species of plants that survived the closure of the prison five plants were chosen to be on display. Each of the five plants has different adaptions to coping with drought, wind, poor soil and sun exposure.
The first plant always receives a lot of attention – Aeonium arboreum, or hens and chicks as most people call it. This succulent is able to store water in its fleshy leaves, and will drop the lower leaves when water becomes scarce. Producing few seeds, the plant mainly propagates itself by the forming roots along its stem. The roots will grow downwards, seeking any soil to root into. The plant is able to thrive in poor soil; I have even seen a massive clump of aeonium growing out of 5 inches of debris that had accumulated on top of a tunnel entrance.
Another popular succulent is Persian carpet. This little beauty is coloring the hillsides of the island pink right now. As tiny as the leaves are, they store water and the slightly dimpled leaves reflect light. The ice plant is great for stabilizing poor soils. Although an ice plant, this little guy is not the common invasive ice plant that is often seen along freeways.
A common garden plant in the 1940s and 50s was Pelargoniums, commonly known as geraniums. Pelargoniums are from the Southern Hemisphere and are from the
Mediterranean regions of South Africa. Five different cultivars survived on the island. The rough leaves reflect light, as well as the plant will drop its lower leaves when stressed by drought. It is not known exactly how, but the scented leaves of pelargonium are thought to be a survival mechanism.
Another survivor is the common garden nasturtium. It is surprising that the fleshy green round leaves are able to cope with the strong winds and lack of water, but these annuals have been self-seeding since they were introduced in 1924. They are able to complete their life cycle by the time water is becoming scarce in the soil.
Many visitors are surprised to see Calla lilies
thriving in the gardens. The callas, growing from a rhizome, are able to grow with the rains and then store energy for next year’s growth. The arrow shaped leaves will even funnel water to the roots. As we don’t water our callas, they do go dormant, the green leaves fading to yellow.
Growing a garden with just native plants is a wonderful goal, but gardeners can also select suitable plants for their area that are not native. Taking a walk around Alcatraz this month really shows how dramatic creating garden on a bare rock with non-natives can be.
Upon arriving to Alcatraz, many visitors are surprised at how, well, BEAUTIFUL, the island is. The gardens are a stark contrast to what they were expecting to find – a barren island in the middle of San Francisco Bay that has the world’s most famous prison. Test your knowledge about the gardens with these questions, I bet you learn something new.
1. In 2005, a plant inventory was done of the surviving vegetation on Alcatraz. How many species of plants were found?
A. Less than 50
B. Between 51 and 100
C. Between 101 and 200
D. Over 200
2. True or False – the island has no source of freshwater other than fog drip and rainfall.
3. True or False – all of the island’s soil was imported.
4. True or False – the gardens have plants from every continent except Antarctica.
5. True or False – inmate gardener, Elliot Michener,
was so attached to the gardens he created during his 9 year stay, that upon his transfer to Leavenworth Prison in Kansas, he requested to come back to Alcatraz to finish his sentence.
6. True or False – today, the garden volunteers have a worm farm in the rose terrace greenhouse.
7. The nasturtiums seen growing on the island today were introduced:
A. 1924 by the California Wildflower and Spring Blossom Society
B. A seagull dropped the seeds
C. 2003 when The Garden Conservancy began clearing overgrowth
8. Alcatraz Island is 22.5 acres in size. The gardens make up:
A. 500 ft2
B. 1 acre
C. 2 acres
D. 4.5 acres
9. True or False – During the island’s days as a military prison, there was a mule stable on the west lawn.
10. True or False – Penitentiary guards would sometimes fish from the Alcatraz dock. They would use the fish heads to fertilize the island’s roses.
11. True or False – Penitentiary inmates tended flower gardens and would leave buckets of flowers on the dock for guards’ families.
12. The garden restoration began in 2003 and relied heavily on volunteer gardens. As of January 2013, garden volunteers have logged:
A. 1000 hours
B. 10 000 hours
C. 30 000 hours
D. 40 000 hours
13. True or False – once you are on the island, the garden tour is free.
14. The military and penitentiary encouraged inmates to garden, mainly to give the inmates something to do. A number of greenhouses were constructed on the island to help grow plants. Today, there are 2
greenhouses on the island, but how many greenhouses once stood on the island?
15. Today, Alcatraz is a protected sanctuary for many kinds of water birds who return to the island every spring to nest and raise their families. A few of these birds began coming to the island during the 40 years when the gardens became overgrown. Which birds come to the island because the overgrowth provides ideal nesting sites?
A. Seagulls and Brandt’s cormorants
C. Snowy egrets and black crowned night herons
D. Pigeon guillemots and penguins
16. True or False – there are still more gardens to restore on the island.
17. True or False – the military had vocational training for inmates to become gardeners.
18. The slope in front of the cell house was planted in 1924 to give a friendly look to San Francisco. The slope was restored in 2007 and the Persian carpet iceplant is blooming bright pink once again. The slope can be seen as far away as:
A. As you approach on the ferry
B. Fisherman’s Wharf
C. Crissy Field
D. The Golden Gate Bridge
19. What is the secret ingredient in our award winning compost?
A. Bird guano
C. Anchor Steam hops
20. True or False – there is always something blooming in the gardens, regardless of the time of year.
1. d; 2. True; 3. True; 4. True; 5. True; 6. True; 7. a; 8. d; 9. True; 10. True; 11. True; 12. d; 13. True; 14. c; 15. c; 16. True; 17. True; 18. d; 19. c; 20. c
How did you do?
15-20 correct answers – You should become a docent!
10-14 – Very good!
6-9 – Pretty good.
0-5 – Come join us on a tour!
It’s a fun time to be a volunteer in the gardens with working on the big projects for this winter. Many of the volunteers got hooked on gardening on the Rock because of the initial uncovering and ‘discovering’ of the forgotten gardens. For people that loves getting dirty and feeling like you are making a difference – this is the time to get involved!
The lawn, which is being prepared to be planted in the Fall of 2013 with native grasses, has become neglected and the ‘green’ of the lawn is all from non-native grasses and oxalis. But even this green vegetation died during the dry summer, leaving a barren looking backdrop to the manicured gardens.
To prepare the area, the first layer of mulch layering has been laid down, and to my dismay, birds have pecked their way through the compost and the cardboard to reach the soil, allowing light to the oxalis that we are trying to suffocate. Those darn birds! I’m hoping to place another layer of cardboard and mulch in the coming week.
In the meantime, the volunteer crew is working away at clearing the forty plus years of overgrowth on the north end of the historic lawn. The overgrowth is being tackled from all sides, and today we finally made it to the base of the large Albizia tree that is in the middle. Another few hours were spent digging up ivy roots and before we knew it, it was 2pm already! As we worked, one of the volunteers wondered out loud if the author of Jack in the Bean Stock was a gardener that had pulled ivy. Some of the ivy shoots were easily 20 feet long!
Clearing ivy is pretty addictive – the work is slow but methodical.
I’ll let you in on a little secret – now is the best time to visit Alcatraz. The Thanksgiving crowds have gone home and the holiday season hasn’t started yet. The ferries are not packed, which means you can buy a ticket the day of. And even better, the island is lush and green, the daffodils are blooming and the hummingbirds are zipping around.
The island feels almost tranquil, especially the gardens. Normally quiet, even during the summer, the Prisoner Gardens on the west side of the island typically only sees visitors when the weather is particularly beautiful. In the winter, it is possible to work for hours in the gardens without saying hello to anyone. So, I had a bit of a surprise while working yesterday on the west side – the gardens actually felt busy. I wondered what was going on and then I realized – people were on the wrong side of the gate – in the CLOSED area!
Following the stream of people, I entered the Laundry Building and spoke to the National Park Service Intern, Nora. It seems like the Park decided to open the building doors and let visitors experience this normally ‘off limits’ shortcut.
This additional visitor access is pretty special – not only do visitors get to see more of the island, but now they can walk around the island through the Laundry Building instead of backtracking. The visitors are also walking in the steps of the inmates – walking through the gardens and seeing the city in the distance while on their way to work in the Laundry Building.
The cliché of being so close yet so far, probably never had a better example.
Even though you will not need to book ahead to visit during the winter months, don’t leave it until the last minute. This area will close for February 1 as Brandt’s Cormorants return to nest in a nearby area.
This week the Garden Conservancy celebrated ten years of our West Coast Council programs. We also gathered to honor Antonia Adezio, our President, who is stepping down in December.
We reflected on our goal of having a bigger impact on West Coast gardeners. Looking around the room Wednesday evening at the close-knit community of gardeners, the Garden Conservancy has certainly excelled at this. In a way, it reminded me of what Freddie Riechel, the first secretary to the Warden challenged himself with when he took on caring for the gardens on Alcatraz back in 1933. Riechel reached out to expert horticulturists to keep the tradition of gardening on the Rock going. The Garden Conservancy has done the same, seeking advice from the West Coast Council and professionals to create educational programs to connect experts to local gardeners and to further develop preservation project gardens.
Antonia joined the newly founded Garden Conservancy in 1989 at the request of Frank Cabot. With the organization firmly established on the East Coast, the board of directors determined that in 202, the organization was ready to have a regional office based in San Francisco. Shortly after, the Garden Conservancy was enticed by the National Park Service and the Golden Gate National Parks Conservancy to form a partnership to restore the Gardens of Alcatraz. The neglected historic gardens quickly became a passion for Antonia. As part of the evening’s ceremonies, I had the honor to present a brief history of our work on the island and to highlight our accomplishments with bringing the gardens back to life.
Antonia’s leadership throughout her time with the Conservancy has shaped the success , especially with Alcatraz, and her vision will be continued as we carry on. I like to think that every garden holds onto some characteristic of their caretakers, even as the caretakers move on. I see this especially in the old gardens on Alcatraz – the surviving apple trees that still bear fruit, the inmate built terraces, and perhaps the greatest mark left – the decision by the Garden Conservancy get involved to restore the gardens for the future enjoyment for all.
I’m constantly learning new things about gardening and Alcatraz, even after working in the gardens for close to six years now. On a recent trip to pick up my order for more volunteer shirts, I finally met David, president of Plum, a company in Emeryville that prints our t-shirts and hoodies. David invited me to take a look behind-the-scenes to see the screen printing process.
David has owned the business for 35 years, first starting to print shirts for museums. A connection then led to the Golden Gate National Parks Conservancy, the non-profit organization that manages the bookstores throughout the Golden Gate National Recreation Area. In fact, sweatshirts for Muir Woods had just come off the line. Plum also prints shirts for various humane organizations.
The screen printing is fairly simple
and hasn’t changed that much since the Chinese invented the process hundreds of years ago. Garments are placed on an automatic rotary printer, with each arm having a screen. The first step in the process is to separate each color in the design to exactly abut each adjacent color so that the colors do not actually touch each other; each color segment is printed separately. This step is now done on the computer, but in the early days of the company each color was hand cut. Each color is then shot on its own screen. Setting up the screens so that this can be achieved is a critical part of the screen printing process. The attached screen forms open areas of mesh that transfer ink which can be pressed through the mesh as a sharp-edged image onto the garment. A fill blade or squeegee is moved across the screen stencil, forcing ink into the mesh openings. The garment is then taken off and is placed on a drying conveyor belt. Depending on the types of inks used, the drier is set at 325 Fahrenheit and dries the shirts in one to four minutes.
David estimates that that they can print over two thousand shirts on one machine in one day!
Elliot Michener, our inmate gardener, would surely have been impressed with the setup. Elliot was a skilled printer himself at a newspaper; or perhaps he was not that skilled afterall, as he tried his hand at counterfeiting money but obviously was caught.
Gardens are all about change – hopefully for the better, but they are never still. With any change, it can almost be expected to face challenges; and this is especially true when you are gardening on Alcatraz.
This week, the gardens saw the installation of a new pipe railing, albeit a pipe rail that was historically there, but had long ago disappeared. The Officers’ Row gardens, opened to the visitors on mid-day Wednesdays suddenly had the new addition seemingly overnight. The approval and installation of the pipe rail was the easy part; getting the pipe rail to the island proved to be the real challenge.
The pipe rail is evident in several photos from the Federal Penitentiary days, and with the obvious hazard, it was approved by the National Park Service review board fairly quickly.
The metal pipe rail was assembled off-site by Heavy Metal Iron and was planned to be brought to the island on an early morning boat. However, at the last moment, the 14’section was denied passage and another plan had to be drawn up. A second attempt was made. This time, the railing was scheduled to be on the early morning barge; but was hampered by the landing at Pier 33 being repaved. The third attempt took advantage of the monthly barge that sails out of Pier 50 and the railing was delivered safe and sound. Success!
Once the railing was on the island, it still had to be hauled up the switchbacks to the gardens. The guys had planned ahead and had brought a dolly to support the railing as they walked up the hill, and the exercise proved to be a good workout.
Installing the railing was pretty simple – coring the concrete to sink the posts, double checking that the railing was sitting level, filing the metal to have a snug fit and then a quick set mortar was used to hold the railing posts in place.
The railing looks like it has always been there and I’m sure the seagulls will be happy to christen it when they return in February.
The garden volunteers are easy to spot on the island with our maroon colored t-shirts and sweatshirts. Proudly worn, our dark maroon uniform with the purple iris cannot be purchased but must be earned by volunteering five times in the gardens. Another source of pride is how faded the t-shirts become –the more faded the clothing becomes indicates a longer tenure, even the holes caused by names tags is something volunteers point out to each other.
But how did our t-shirt come to be? Why was an iris chosen to represent the volunteer gardeners and the restoration work?
I spoke with Bill Prochnow and Vivian Young, graphic designers for the Golden Gate National Parks Conservancy to learn more.
The logo was developed in 2004 after the restoration project began in November 2003. In keeping with the existing park logos created by Michael Schwab, the iris graphic was designed to be fairly simple with bold colors and a strong black border. The Douglas iris drawing had already been designed by Vivian in 2004 for another project within the park, but had not been used. With iris being one of the survivor plants on the island, the decision to use the iris to represent Alcatraz was logical. Coincidentally, Douglas iris had been planted on the island by a group of BoyScouts in the early years of the island becoming a National Park, but had perished over the years. Amazing, a new clump of Douglas iris found its way to the island along the Main roadway and has flowered for the past two years.
Superimposing the iris image on the outline of the island’s silhouette tailored the graphic to represent the gardens. Reading into the images, the creation of the final graphic is perfect for the Gardens of Alcatraz – the harsh prison is softened by using yellow and the iris (the plants) dominate. A contrast to what visitors to the island expect to see.
The maroon color of our t-shirts was chosen by the late Carola Ashford, the gardens first Project Manager, simply because it was her favorite color. With a gift for color combination, she chose well as the maroon blended perfectly with the yellow and purple.
The start of the project was focused on removing vegetation to restore the gardens; so the wording on the shirts was worded ‘Alcatraz Garden Restoration’. The wording has since changed to ‘Gardens of Alcatraz’ to reflect that now there are gardens again to see and enjoy.
While our volunteer t-shirts still must be earned, we now offer a light lavender color version of our t-shirt for purchase in the island’s bookstores and online. The sale of our t-shirt helps to support our preservation work on the island.
Curious visitors sometime ask ‘How does stuff get to the island?’ While picking up a truckload of chicken manure from a nearby store, I thought “Maybe I’ll do a blog about following the manure from the store to the island”.
I completed my purchase and then proceeded to Pier 50, home of WestStar, the barge company that runs the monthly supply run out to the island. The bags of manure were unloaded by hand into wooden boxes and then stacked with the rest of the Alcatraz supplies in the warehouse. Supplies can be dropped off and stored in the warehouse a few weeks prior to the barge run.
I arrived bright and early this past Tuesday
morning at Fort Mason at 3:30am to carpool with other Alcatraz staff back to Pier 50 to board the tug that tows the barge (after a mandatory stop for coffee and donuts). Donning life jackets, we hopped from the dock onto the barge and then climbed down a ladder to get onto the tug. Once aboard, we tucked into the donuts for the 30 minute trip to Alcatraz. I was hoping for a view, but the only view was out the bathroom window porthole, which someone had creatively drawn a few fish.
Pulling up to the Alcatraz dock, the barge was secured and we climbed onto the Alcatraz dock. According to Patrick McAllister, Director of Alcatraz Operations for the Golden Gate National Parks Conservancy, this month’s barge supply was fairly small compared to others. A typical barge brings over bottled water, merchandise for the island’s three bookstores, empty dumpsters, and various construction equipment and building materials. The uploading of the barge is orchestrated to be finished by the time the staff boat docks at 9:00am.
The two big safety lessons were 1) watch the hook from the crane and 2) make sure your feet are clear of the palette when it is set down.
Two forklifts were unloaded first, and started to shuttle supplies to where they needed to be on the island. McAllister developed a rough system to avoid the supplies from piling up in the vincinty of the dock. As palettes were lifted one by one by the barge crane onto the Alcatraz dock, the forklifts kept up a relay back and forth. WestStar workers hooked each palette to the crane while Parks Conservancy staff waited on the dock to unhook the ropes that held the palettes.
Soon, the barge was empty; and then materials that were being shipped back to the city were loaded. Empty water bottles, full dumpsters and a generator along with stacks of empty palettes were being shipped back. The most interesting was seeing the generator being roped onto the hook and then lifted onto the barge.
In the beginning of the garden restoration, all the supplies for the gardens were imported this way – countless bags of gravel for the rose terrace, concrete mix for the new railings, the greenhouse kit, even plants if they were dropped off the day before at Pier 50. It is an amazing amount of effort that it takes to keep the island going. Today, it is relatively simple, the barge itself has only been postponed a few times due to bad weather. I can only imagine what an undertaking getting building materials to the island when it was a military fortress in the late 1800s, before the convienance of tugs and forklifts.
This past Friday the Garden Conservancy hosted a meeting for the Bay Area Gardens Network (Bagnet). Bagnet is represented by all the major public gardens in the Bay Area. Gardens from UC Botanical Gardens, Cornerstone in Sonoma, Filoli, Mendocino Botanical Gardens, Presidio Trust, and Merritt Lake in Oakland, just to name a few, attended. Looking around the room, it was impressive to see the wealth of knowledge that was gathered. We started the meeting by introducing ourselves by stating 1) where we worked, 2) what we liked most about our work, and 3) what we least liked about our work. Going around the room, the common answers were for most liked – seeing visitors enjoying the gardens; while the least liked typically involved budget cuts and wearing multiple hats to get the job done.
The idea of a Bay Area garden group started in 1996 and was the idea of Richard Turner, editor of Pacific Horticulture magazine. Turner saw a need for Bay Area gardens, of all sizes and types, to keep in touch with each other and discuss various issues that everyone faces among gardens; as well as providing an excellent network for staff of all the gardens. With many unique gardens around the Bay Area, it is worth promoting and helping each other, instead of feeling the need to compete for visitors and resources.
The day’s agenda had a few topics of great interest; one being creating a more comprehensive website that lists all the Bay Area gardens and activities scheduled. Currently, a website does exist, www.bayareagardens.org, led by Pacific Horticulture. Updates are being planned for this website so stay tuned!
I had the pleasure to update the group on the progress of the Gardens of Alcatraz for the past five years – in 10 minutes! I had a lot to cover but I managed to fit in the highlights – accomplishing five garden area rehabilitations, logging 40 000 volunteer hours to date, noting our sustainability achievements of the water catchment and composting sites; and describing our outreach efforts – 8 new waysides around the island, the self-guided brochure, free docent tours twice a week and the ‘Ask the Gardener’ open garden on Wednesdays; as well as providing our garden t-shirt for purchase in the bookstore and receiving a royalty on each one sold, and our ever-improving website, including this blog! Whew! A lot has been done.
Chatting with members afterwards, many people commented on some aspect of my presentation that they had experienced themselves or were considering undertaking. In the afternoon, the group was toured through the Presidio by Michael Boland. We were fortunate to have him for the afternoon as he showed us the natural areas that had been rehabilitated, the community involvement taking place, as well as the infrastructure of the Doyle Drive bridge construction project, going through the historic Presidio.
Through the course of the afternoon, I realized that Alcatraz is not really an island. Michael’s history of the military in the Presidio linked Alcatraz to that key time period when the military landscaped their bases, when much of Alcatraz was planted. Island residents were focused on gardening and improving their home. Even today, Alcatraz is connected by being part of the garden network in the Bay Area. This of course, made me realize that even though I work on an island, I’m not isolated in my challenges, and that any success achieved benefits all the area gardens with the sharing of knowledge.
