Most species in this genus are hardy perennials, but some outstanding hybrids, developed form Penstemon hartwegii, are half-hardy annuals in most of North America and make good bedding plants. With their long spikes of tubular red, pink, purple, and white flowers, penstemons are an attractive halfway house between foxgloves and snapdragons.
