Wilcox's penstemon thrives in well-drained soil with partial shade to full sun exposure in cool, temperate climates of the Pacific Northwest. Water regularly during the growing season but avoid waterlogged conditions, which can cause root rot. It is a low-maintenance native perennial that rewards gardeners with tubular blue-purple flowers attractive to hummingbirds and pollinators.
