Penstemon 'Raven' (Bird Series)
beard tongue
Elegant spikes of small, tubular, foxglove-like flowers appear from July to October among lance-shaped, bright green leaves.
This easy-to-grow perennial will quickly form large, leafy clumps and is perfect for adding a splash of colour to the middle of a sunny, well-drained border. If you deadhead regularly, the flowers of Penstemon 'Raven' will persist until the first frosts.
The rich, deep purple flowers of this variety contrast particularly well with purples and acid greens.

How to care for Penstemon Raven (Bird Series):
Plant penstemons in well-drained soil in a sunny or lightly shaded position, incorporating compost or well-rotted manure to improve fertility. Water regularly until established, then reduce watering, as they prefer drier conditions once settled.
Deadhead faded blooms frequently to extend the flowering season. In autumn, leave the top growth in place to provide winter protection, then cut back in spring when new shoots emerge lower down the stems.
Apply a dry mulch, such as bark or composted straw, around the base in colder regions to insulate the roots from frost. Every few years, lift and divide congested clumps in spring to maintain vigour and encourage fresh growth.
