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).

Description


Annual, slender taprooted herb.

Opposite, sessile, palmately lobed leaves, leaf segments linear-elongate.[1]The leaves of the inflorescence larger and often more lobed than the cauline leaves.[2]

Inflorescence dense, bracteate heads, flowers subsessile, corolla tube 12-30 mm, flowers pink to white, generally bicolored. Calyx more or less glabrous, sometimes scarcely hispid on outer surface or with marginal cilia.[1]

Fruits are 3-chambered capsules, bearing several seeds per capsule.[2]

From Greek lepto, narrow, siphon, tube, for shape of corolla tube.[1]

Bloom Period


April- June[3]

Distribution


West Cascades, southwest B. C., to California, east through the Columbia Gorge, and east side of Cacsades in Oregon.[1]

Habitat


Open, grassy places at lower elevation.[1]

Seed


Seed sample from: 2011
