Phacelia hastata, commonly known as Silverleaf Scorpionweed, is a perennial herb native to a variety of habitats in western North America, including sagebrush desert, dry mountain slopes, and alpine meadows, from British Columbia and Alberta south to California and east to Nebraska. It is adapted to high elevations, up to 13,000 feet. This species typically grows to a height of 12 to 24 inches (30 to 60 cm) and spreads 12 inches (30 cm) wide. Silverleaf Scorpionweed has distinctive deeply veined, gray-green leaves that are covered with fine hairs, giving them a silvery appearance. From late spring to early summer, it produces showy cymes of white or lavender flowers that are attractive to pollinators such as bees.

In cultivation, Phacelia hastata is valued for its drought tolerance and ability to thrive in poor soils, making it suitable for xeriscaping and naturalistic plantings. It is often used in wildflower gardens and as a border plant in areas with dry, sandy to rocky soil. It requires minimal maintenance once established and can be grown in full sun to part shade. While it is not commonly afflicted by diseases, it can be susceptible to root rot in poorly drained soils. Gardeners should be aware that Phacelia hastata can self-seed prolifically under ideal conditions, potentially becoming weedy.CC BY-SA 4.0
