Phacelia hastata is a species of phacelia known by the common name silverleaf phacelia. It is native to western North America from British Columbia to California to Nebraska, where it can be found in many habitat types, including flat scrublands, mountain forests, and alpine talus.
[edit] Description
Phacelia hastata is a perennial herb variable in appearance. It produces a hairy stem which grows decumbent or erect to a maximum height near half a meter. The leaves are lance-shaped or oval, smooth-edged, lobed, or divided into leaflets. They are hairy, prominently veined, and generally low on the plant. The top of the stem is occupied by the inflorescence, which is made up of a few to a great many one-sided coiling "scorpioid" cymes of flowers (see image at top left). Each flower is roughly half a centimeter long, generally bell-shaped, and whitish to pale purplish in color. It has five protruding stamens and a calyx of narrow, hairy sepals.
There are about four subtaxa.
- Charleston phacelia, var. charlestonensis, is endemic to southern Nevada.
- Timberline phacelia, var. compacta, grows in the mountains at 7000 to 13,000ft, and is usually under 10" tall.
