Penstemon Blackbird is one of the darkest flowered Penstemon, with clusters of large, dark purple, trumpet-shaped blooms held on strong stems above green semi-evergreen foliage from May to October, often longer. If you only have space for one plant in your garden, we believe Penstemon is a good choice. A real must have for any garden, giving you colour for up to six months of the year, sometimes longer. Penstemon are the insomniac party lovers of the plant world which do without sleep for six months of the year. Summer arrives and your Penstemon start flowering, summer ends and they are still blooming, autumn comes around and they still show no signs of tiring. Tell them the party is over and they will just laugh! You will not need to battle against slugs and snails either, as Penstemon are not eaten by any garden pests and yet loved by bees. These gorgeous plants do not mind drought or heavy rain and are perfect for containers, borders, in sun or part shade. Being a hardy perennial, Penstemon Blackbird does not require any winter protection in most of the UK and will reach a height of approximately 80cm, spreading to between 45-60cm.
