Penstemon have become incredibly popular and understandably so, as they have such an easygoing nature and unbelievably long flowering period. There is even an international Penstemon society whose members are known as Penstemaniacs.
Flowering from May to November (and often longer) over semi-evergreen foliage, they are trouble free and resistant to slugs and other garden pests. They spread to around 45-60cm (18-24”), are unfussy on soil conditions in sun or part shade, are happy in either a border or container and attract pollinating insects into the garden. Hardy perennial. Delivery April onwards.
