Penstemon 'Onyx and Pearls' is a striking herbaceous perennial known for its dramatic upright habit and intense color contrast. It features dense, near-black foliage that forms a bushy clump reaching up to 42 inches in height. In early summer, tall spikes of iridescent lavender-white, bell-shaped flowers emerge, attracting hummingbirds and bees. This hardy cultivar thrives in full sun and well-drained soil, exhibiting excellent tolerance to drought, heat, and humidity once established.
