Gardening Trends from 1900s through the 1910s
The second in this “Historic Gardening Trends” series, we are now moving out of the 1800s and into the 1900s. The 1900s through the 1910s had their own gardening trends; building from what was popular during the Victorian era but rejecting and changing what new gardeners did not like about the style. Alcatraz itself was going through a change. The Civil War had brought a rapid amount of development and change in the structures, trickling down to the gardens. The construction of the main concrete cell block began in 1909 and, once again, the wives of the soldiers sought a way to bring life and civilization to the Rock via gardens.

By the end of the 19th century and the beginning of the 20th century, there was a trend to return to formal gardening. There was no longer a desire to have a “garden growing wild” aesthetic. The plants were often carefully pruned and nurtured to be contained. Furthermore, there was more of an effort to use architecture in gardening. With building projects being wider-spread, people sought to show off their house and its features, using the garden to direct the eye. Similarly, using concrete terraces, paths, and steps provided a bit more structure and more of an architectural feel. The Victorian tradition of using gardens as an outside room continued and would continue to be a hallmark of modern gardening practices. Gardens were places to gather with family and friends, not just a place to grow food. Water was another major feature in the early 1900s gardens. Fountains, pods, and waterfalls were popular.

The plants themselves were almost an afterthought to the garden. Gardeners used geometric lines and an enclosed feeling to make the outside feel more like the inside. Furthermore, the Victorian fascination with wild, sprawling exotics was replaced with neat, boxed hedged beds. The actual flowers and shrubs were kept off verdant laws and bowling greens. It was no use having people over to your garden if they could not walk around without stepping on flowers.
Inside these neat and tidy beds were a variety of peonies, irises, lavender, erigeron, and foxgloves. The colors were muted but more diverse than the Victorian era’s use of mainly greens, pinks, and purples. Roses were common as well. However, instead of ramblers and creepers allowed to sprawl and climb, they were contained into neat, round bushes.
The modern gardens of Alcatraz have these early 1900s touches hidden throughout. The water features are easy to spot since this is an island and the ocean serves that purpose nicely. The foxgloves can be found most commonly in the Rose Garden. While there are creepers and ramblers all over, other rose bushes, such as those in Foundation 8 of Officers’ Row, are kept rounded and contained. Lavender can be spotted peaking through in Foundation 9. The Toolshed Terraces gardens bring forth a more architectural element to these gardens, a subtle call back to the terraces commonly used during this time period.
What is perhaps most in line with the gardening style of the early 1900s is the fact that the gardens serve as a backdrop to the architecture, the prison. Instead of the garden being a separate entity, it is tied to, and often overshadowed by, the main cellhouse. The beds along the pathway are contained and wind around following the road; they are not allowed to grow wild and eclipse the cell house. As gardeners, we sometimes forget people come to Alcatraz not for the gardens, but for the prison. In the 1900s, the gardens were also there as a second thought; meant to enhance life and beauty on the island. It moves away from the “natural” and into the backdrop. These gardens have their own beauty and serve another purpose. But the combination of styles from such a long period of time is what allows the Gardens of Alcatraz to be diverse and beautiful, to represent a time and provide a look back as to what life would have been like for the families living on the island, and not just the prisoners and guards.

The Iris: A Centuries Old Flower with an Intriguing History
One of the most beautiful groups of flowers we have on Alcatraz is the iris. They have been a common staple in gardens for centuries. It is worth taking a moment to look at the long history of these flowers and when they became common garden staples in America.

Irises first grew to prominence as a garden flower in 1469 BCE. The Egyptian pharaoh King Thutmose III conquered Syria, where irises grew. An avid gardener, he brought them back to Egypt to be cultivated. This was the first-time irises had been documented as a gardening flower. From there, irises rose to prominence for their religious significance. They were carved into sculptures at temples and doctors used the rhizomes for medicine and perfume offerings.
As irises began to spread in the popularity, due to their showy flowers and lovely scents, the Greeks were the first to name them “iris”. Iris means rainbow and is the Greek messenger of the gods. Indeed, irises come in an array of colors, from deep purples to brilliant oranges. They continued to spread around Europe, becoming a staple in gardens from Spain to parts of Asia. Indians began to use their rhizomes for religious offerings. In Florence, Italy, the scent became a popular perfume. The iris inspired the design for the Fleur-de-lis. It is a common motif in France, past French Colonies, and with the Catholic Church, usually relating the Virgin Mary.

The first documented iris in America was in 1600s Virginia. From there, irises would continue to hybridize, speciate, and transform into unique American varieties. It wasn’t until Michael Foster (1836-1907) studied and planted these beautiful flowers, that irises were made popular. One of his students, William R. Dykes (1877-1925) took an interest in irises and published a book called “The Genus Iris”. It was this study of irises that brought the flower to the popular conscious. In the early 1900s, there was a rise of irises in American gardens. It became so popular, Tennessee adopted it as the state flower. The most popular iris today is the German or Bearded Iris, an iris we have on Alcatraz. However, most irises have hybridized so much that there are 300 species, and these species are difficult to separate into a clean taxonomy.
The hybridization provides another unique focal point for Alcatraz’s irises. If you smell a modern iris, it doesn’t smell like much. On Alcatraz, the irises have a stronger scent. Different Alcatraz irises smell like root beer, vanilla, and grandma’s perfume (according to
some visitors). We have pastel purple, deep purple, white, orange and yellow Irises scattered about the Rose Garden and Officers’ Row. We use heirloom plants, which means our irises still have the genetic markers to make scent. Our use of heirloom plants provides an extra touch of historical intrigue to visitors who know their flowers.
As a flower, irises inspire the creative and bring delight to the floral enthusiast. They provide intriguing patterns and interesting shapes. They are unique and vibrant against the backdrop of stone and concrete. They are a flower with a long history, and it’s not hard to see why they’ve been a garden staple for thousands of years.

Time for Dividing
Late winter and early spring are ideal times to divide perennials on Alcatraz. As we do not (typically) receive frost, plants never go fully dormant as in northern climates, but herbaceous plants do slow their growing of new leaves. This window is perfect for dividing bearded iris. The plants have not yet put valuable stored energy into producing new leaves, and instead can expend energy into forming new feeder roots once it has been replanted. Once established, new leaves are produced. We have found that mature clumps of iris will still flower the same year that they were transplanted, but smaller pieces of an iris rhizome may take up to two years to flower.
Generally, we aim to divide our iris

every three years, just like the Ruth Bancroft Garden does with Ruth’s heirloom collection of iris. Happy iris become overgrown and the thick rhizomes start to crowd each other, growing over top of one another. Overgrown iris can lead to several problems – poor air circulation which increases rust on the leaves, the roots competing for nutrients in the soil, and the centers of the iris clump will become bare of leaves and not produce any flowers at all. It’s easy to tell when you should take on the project of dividing your own iris if you look for these signs.
The garden volunteers divided the tall scented bearded iris in the Prisoner’s gardens this week. Four separate patches of iris were divided, and we ended up with not only the beds replanted, but with five bins of extra iris!

The iris bloomed really well last year, but as we add fresh compost to enrich the soil, the rhizomes were becoming buried. Iris likes to be planted very shallow, with the backs of the rhizome sitting above the soil.
One of the volunteers showed me an interesting feature about the rhizomes that I didn’t know before. Looking at the underside where the roots grow from, holes are visible. These were where the roots had grown from. The rhizome grows from one end, and the older end becomes a storage unit for energy (much like a potato). When dividing iris, the older sections are broken away and only the piece with the roots are kept. We are curious to see if the older section will sprout roots, so we placed a few in a pot in our greenhouse to see what happens

Now we are busy trying to find new homes for the divided extras, these are my favorites and I can’t bear to compost them.
