Quick look

Phacelia sericea, the silky phacelia, blue alpine phacelia, or purple fringe, is a showy perennial species of Phacelia endemic to western North America. It grows mainly at subalpine to alpine elevations in forest openings or above treeline among rocks and sand. Sericea comes from the Latin sericeus, or silky, referring to the fine hairs on the leaves and stem.
