Answer: One of my references says that Zauschneria californica is the same plant as Epilobium canum canum; another says they are simply related. It's odd, because my plant encyclopedia says that Epilobium prefers a moist soil, while Zauschneria thrives in dry soils.
I found Zauschneria latifolia (Hummingbird Trumpet) in the mail-order catalog Southwestern Native Seeds, Box 50503, Tucson, AZ 85703 (there is no ph# listed). The catalog is outdated, so you'll have to check to see if they still have the seeds. According to the NY Botanical Garden's encyclopedia, hummingbird trumpet is the same as California fuchsia. It also states that this plant thrives in the dry, stony soils of California and Baja California.
A few other places to try are: Las Pilitas Nursery, Santa Margarita, CA ph# 93453, and Freshwater Farms, Eureka, CA ph# 707-444-8261. I'm sorry I can't be of more help! I hope you find them!
