Rainy Side Notes
Valerie Easton, a garden writer in the Pacific Northwest, once wrote, “I was so pleased with both the color and size of 'Storm Cloud' I don't see a reason to grow any other kind of agapanthus. I whole-heartedly agree. If you could grow only one, this would be the agapanthus of choice. This hybrid is a stunning addition to the garden. Hybridized in 1943 by Jimmy Giridlian of Arcadia, California, this handsome plant is drought tolerant, adding deep blue to purple flowers on top of four-foot stems to the garden during our typical drought season from July to September.
This plant is long lasting as a cut flower for the vase, and the blossom heads are excellent as dried flowers. The genus name, agapanthus, comes from the Greek words, agapao—love, and anthos—flower. Some parts of the plant are poisonous when ingested, and may cause allergic reactions or skin irritation when handled.
As with most agapanthus, grow the plant in well-drain soil and protrect from harsh winds.
