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]
Description
Phacelia hastata is a variable perennial herb with a stem 5 to 50 centimeters long.[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.[5] Most of the leaves are in a tuft around the base of the plant.[3] The flower has an urn- or bell-shaped white or lavender corolla about 4 to 7 millimeters long. The stamens protrude. The fruit is a hairy capsule a few millimeters in length.[5]
