Product Details

Rock Candy Purple Penstemon

Penstemon barbatus 'Novapenpur'

Rock Candy Purple Penstemon brings clear, saturated purple color on upright flower spikes that rise cleanly above the foliage. The blooms are neatly spaced along the stems, giving the plant a crisp, vertical rhythm rather than a dense mass. Its compact clump keeps everything contained while still adding height where needed. Reaching about 12 to 18 inches tall and spreading 12 to 18 inches wide at maturity, it forms a tidy, upright presence that fits easily into borders, accents, and mixed plantings.
