Seeds were sown into cone-tainers filled with Sunshine # 1 (a soil-less, peat-based media) amended with micro-nutrients (Micromax) and a slow-release fertilizer (Osmocote 14-14-14). Flats of conetainers were placed in greenhouse set at moderate temperatures (70 degree days/50 degree nights.) Seeds germinated readily with no treatment. Most seeds germinated within one to two weeks. (Leptosiphon grandiflorus also needed no treatment before germination).

From Greek lepto, narrow, siphon, tube, for shape of corolla tube.[2]

Bloom Period

April- June[4]

Distribution

West Cascades, southwest B. C., to California, east through the Columbia Gorge, and east side of Cacsades in Oregon.[2]
