Dodecatheon HendersoniiAlso called "sailor caps". Dodecatheon hendersonii has basal clumps of leaves, 2-16 cm, with nodding flowers. The stamens are thrust out with the sepals bent back. Dodecatheon are mostly from North America. The flowers are magenta to deep lavender to white. It is highly variable and hybridizes with Dodecatheon clevelandii. D. hendersonii is summer deciduous, dying back to the ground after the rains cease. Distribution A large part of California to southern British Columbia and Idaho. In California: Northwestern California (except North Coast), Cascade Range, Sierra Nevada Foothills, Great California Central Valley, San Francisco Bay Area, north Inner South Coast Ranges, San Bernardino Mountains. Food The leaves and roots can be eaten when roasted or boiled, but are reported to be poisonous when eaten raw. Cultivation D. hendersonii needs good drainage, and needs a dry summer period. For Dodecatheon, plants germinated from seed may take 3-5 years to produce flowers. For some Dodecatheon, with frequent light fertilization and moisture, dormancy may be delayed, and flowering time may be decreased to 1-2 years. Another technique to speed flowering is to place them in a cooler after dormancy, then bring them to a shadehouse in midsummer. It can be grown by division in winter. It prefers shade when inland.
