(Beard Tongue) Penstemon ROCK CANDY® Blue is a delightful compact perennial that adds a burst of brilliant blue color to sunny gardens. Its upright spikes are covered in masses of bell-shaped flowers ranging from soft cornflower to lavender-blue, creating a soothing yet vibrant display from late spring through summer. The bright blooms rise above tidy mounds of green foliage, offering structure and charm in borders, containers, and pollinator plantings.

This hardy beardtongue grows about 12 to 18 inches tall and wide, making it perfect for the front of flower beds or mixed perennial combinations. The blooms are highly attractive to hummingbirds, bees, and butterflies, adding life and motion to the garden while the plant’s natural resistance to deer keeps maintenance low.

Thriving in full sun and well-drained soil, ‘Rock Candy Blue’ performs best in conditions that mimic its native dryland roots. Once established, it’s heat and drought tolerant, making it an excellent choice for low-maintenance landscapes and summer color that lasts.

Hardy in zones 5 to 8, Penstemon ROCK CANDY® Blue combines compact form, extended bloom time, and irresistible color appeal making it a standout perennial for sunny borders, cottage gardens, and rock gardens alike.
