Royal penstemon is a stunning native perennial known for its large, brilliant blue tubular flowers that put on a spectacular show in late spring and early summer. It thrives in full sun with well-drained, even gravelly soil and requires little supplemental water once established in its Great Basin and Pacific Northwest home range. This plant is a magnet for hummingbirds and native bees, making it a standout addition to pollinator gardens.
