In California, it occurs in the northwest (except the north coast), the Cascade Range, the Sierra Nevada foothills, the Central Valley, the San Francisco Bay Area, the north Inner South Coast Ranges, and the San Bernardino Mountains. It is generally found in open woodlands, from sea level in British Columbia, up to {{convert|1900|m|0|abbr=on}} altitude in California. Common names include broad-leaved shooting star, Henderson's shooting star, mosquito bills, and sailor caps. D. hendersonii is summer deciduous, dying back to the ground after the rains cease. It has basal clumps of leaves, 2–16 cm, with nodding flowers 6–25 mm long on stems 10–30 cm tall. The flowers are magenta to deep lavender to white, with the stamens thrust out and the sepals bent back. It is highly variable and hybridizes with Dodecatheon clevelandii, from which it can be distinguished by its reddish or purplish stem. CultivationIt needs good drainage, and needs a dry summer period. 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 propagated by division in winter. It prefers shade when inland. This plant has gained the Royal Horticultural Society's Award of Garden Merit.[1][2] UsesThe leaves and roots can be eaten when roasted or boiled, but are reported to be poisonous when eaten raw.
