Cache Penstemon (Penstemon compactus) is a rare, low-growing perennial endemic to the Mount Naomi Wilderness area of Cache County. It features leathery, lance-shaped leaves and blooms from June to August with dense, compact clusters of vivid electric blue-purple tubular flowers that pop in any landscape! Drought-tolerant once established, it thrives in full sun conditions. Staying compact at just 3 to 8 inches tall, this penstemon forms tidy, evergreen tufts perfect for dry garden beds and borders, rock gardens, alpine plantings, pollinator beds, and erosion control on dry slopes.
