Phacelia hastata is a species of flowering plant in the borage family, Boraginaceae. Its common names include silverleaf scorpionweed,[1] silverleaf phacelia,[2] and white-leaf phacelia.[3] It is native to western North America from British Columbia and Alberta south to California and east to Nebraska.[1] It can be found in many types of habitat, including scrub, woodland, and forest, up to an elevation of 13,000 feet.[4] It prefers sandy to rocky soil.[5]
Description
Phacelia hastata is a variable perennial herb with a stem 5 to 92 centimeters (2 to 36 in) long.[6][5] It is coated in a fine, silvery pubescence.[3] The deeply veined, gray-green leaves are lance-shaped to oval, and smooth-edged, lobed, or divided into leaflets.[6] Most of the leaves are in a tuft around the base of the plant.[3] The flowers are arranged in cymes, blooming in early summer.[5] They have an urn- or bell-shaped white or lavender fused corolla about 4 to 7 millimeters long. The stamens protrude.[5] The fruit is a hairy capsule a few millimeters in length.[6]
There are up to four accepted varieties:[2][7]
- P. hastata var. charlestonensis – Charleston phacelia, Spring Mountains phacelia; endemic to Nevada[8]
- P. hastata var. compacta – compact phacelia, timberline phacelia; a matlike form occurring at elevation[9]
