Scouler's shrubby penstemon thrives in well-drained, rocky or sandy soils with partial to full sun and minimal supplemental watering once established. Plant it in a rock garden or native border and avoid overwatering, which is the most common cause of failure. It rewards low-maintenance gardeners with lavender-purple tubular flowers that attract hummingbirds and pollinators in late spring.
