The RHS Penstemon Collection

Penstemons have become so popular in recent years - small wonder given the wonderful colour range, long flowering season from early summer to mid-autumn, adaptability and ease of maintenace of these stunning perennials. Equally at home in formal border and cottage garden settings, no garden is too small, or too large, for a few Penstemons. Our collection features only semi-evergreen cultivars which have received the Society's Award of Garden Merit.
