Phacelia bolanderi, commonly known as Bolander’s Phacelia, is a deciduous perennial herb that thrives in the understory of coniferous forests, along streams in riparian zones, and in chaparral and scrub habitats of the Pacific Northwest, including Oregon and coastal northern California. It typically grows to a modest height of 1-2 feet (30-60 cm) with a similar spread. Bolander’s Phacelia is characterized by its deeply lobed and strongly toothed leaves, which are reminiscent of grape leaves, and its clusters of inch-wide flowers that come in shades of purple, lavender, or blue. The plant is notable for its late flowering period, often blooming during the peak of summer when many other species have finished their display.

This species is valued for its ability to provide color in the garden during the hot summer months when few other plants are in bloom. It is suitable for wildflower gardens, native plant landscapes, and as a border plant in drought-tolerant gardens. Bolander’s Phacelia is adapted to a range of soil types and is particularly drought-resistant, requiring very low amounts of water once established. It prefers full sun to part shade and can tolerate a variety of drainage conditions. While it is generally low-maintenance, it can be susceptible to powdery mildew in humid conditions.CC BY-SA 4.0
