Penstemon 'Stapleford Gem'
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, and award-winning 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 deadheaded regularly, the flowers will persist until the first frosts.
The magenta-blue flowers of Penstemon 'Stapleford Gem' have a metallic sheen, reminiscent of black grapes, which contrasts particularly well with deep purples and blues.

How to care for Penstemon Stapleford Gem:
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.

This perennial is semi-evergreen so it can lose some of its leaves in winter. In colder regions or more exposed gardens, it may lose them all, but then fresh new growth appears again in spring.
