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.

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.
