Spring in Northern California is well underway. The daffodils have another week or so of blooming and then we will be planting our summer annuals. Our greenhouse is bursting with plants ready to be planted outside.
Many old fashioned annuals are easy to start from seed.
We have had great success with pot marigolds (Calendula officinalis), snapdragons (Antirrhinum majus), Shirley poppy (Papaver rhoeas), bachelor’s button (Centaurea cyanus), and Zinnia elegans.
One of my volunteers started blue columbine (Aquilegia) and they are doing fantastic. Often gardeners find that columbine prefers to re-seed itself in cracks in sidewalks, but is fussy when given the perfect potting medium. Just like former residents, my volunteer collected seed from her beloved garden in Philadelphia and brought them with her to her new home in San Francisco.
Last spring we collected seed from the survivor grape hyacinth (Muscari armeniacum) just to see if we could get some to germinate. The seed heads were dried and then crushed to release the seeds. We researched the best methods to grow the plants from seed and found recommendations that the seeds be soaked in water first. We collected enough seed that we decided to do an experiment – soaking seeds and not soaking the seeds. We found that the soaked seeds did produce more seedlings; but we also had the dry seeds sprout. It will be interesting to see how long it will take for these new seedlings to flower.
We are also trying to propagate Fuchsia paniculata, but these are proving to be a challenge. So far, we have done 30 cuttings and only two are showing promise.
Our token tomato plant is doing well, going into its second year. We have one historic photo from the 1950s of tomatoes being grown in Officers’ Row. We have tried growing tomatoes again in the garden but in the chilly summer fog, the plants are not happy. I only wish we could find photos of lettuce and cool season veggies; so that we could historically grow them as well. But, residents primarily chose to grow flowers to brighten up their landscape and to have cut flowers in their homes.
The gardens are delighting visitors again this year, especially the inmate gardens on the west side of the island. Be sure not to miss them when you visit!
