Visits to the Rock are not always quite this warm and sunny but when they are, it makes the trip even more enjoyable. Don’t forget to pack some extra clothing too because the area can become windy.
The first plants you’ll see while you are still on the boat are the Century Plants, or Agave parryi.
|Aeonium species and hybrids as well as Jade Plants (Crassula argentea) can be seen all over the island.|
|This Australian Tea Tree (Melaleuca alternifolia) is most likely the oldest tree on the island. There are also several Dragon Trees (Dracaena draco) that were also planted by members of the military that were stationed here between 1850-1934.)|

|The oldest Fuchsia on the Rock, this specimen is 70 years old.|

One of the advantages of the garden tour is that you are taken off the beaten path to admire all of the hard work volunteers have done over the last decade or so as they’ve improved gardening conditions. An extra added plus is that you get to see this! It’s the official compost area on Alcatraz!
This compost has even won some ribbons at the Marin County Fair! What’s not to love about that right?
With the help of the The Garden Conservancy the program here has truly flourished.
Limited to using historically accurate plant materials what’s wonderful is that after all of the overgrowth was removed from many of the gardens long overshadowed plants and bulbs started to return. With each new discovery we’re all learning more and more about how the island’s occupants once gardened. It is also a testament to the hardiness of many of these plants.
This rose was one of the amazing plants to be rediscovered on the island. Actually, it is probably the most important rediscovery. It is what’s called the Welsh Rose and up until 2003 it was thought extinct. That’s when this specimen was discovered on the island! Since then propagation work has been done and work has continued.

Just above the compost and greenhouse level on the east side of the island are the last rows of gardens that were created around and in between the houses that once stood above the citadel. During my last trip I’d wanted so badly to wander down to them but due to the narrowness of the stairways and the unevenness of the paving they are too unsafe for the general public to walk around so be sure to take a tour! That’s the only way to gain access to these areas.
The plants in these little alcoves are very much the plants of gardeners who wanted to cheer up their isolated little spot in the bay. They were the first gardens of Alcatraz, but certainly not the last.
Just beyond the terraced area is the last portion of the earliest gardens and it is a bit more windswept and wild since it is at the top. Like the area below it, the housing structure has lost its wood to fire of uncertain cause and all that remains is the concrete skeleton.

|Note how the Jade plant (Crassula ovata) has its trunk partially in the shade. This adaptation also allows the plant to remain protected from the wind.|
|The hummingbirds of Alcatraz.|
I should add that many of these areas were maintained by the prisoners of the Federal Penitentiary era but I will say more about that tomorrow.
