Penstemon
Hardy and half-hardy herbaceous perennials and sub-shrubs.
Hardy alpine types are suitable for rock gardens or front of borders; half-hardy taller types require sheltered, well-drained sites and possibly some winter protection. Relatively short-lived plants that will not tolerate wet conditions. Snapdragon-like, open mouthed flowers of many colours in upright racemes.
