Penstemon Sour Grapes

Its unusual colouring makes Penstemon ‘Sour Grapes’ instantly recognisable. This well loved variety bears upright spikes of alluring bell-shaped flowers in a peculiar blend of pink and blue, being neither one nor the other. This hardy semi-evergreen perennial is easy to grow, blooming over an exceptionally long period. Penstemons make a colourful contribution to herbaceous borders and wildlife areas where they will attract bees and other pollinators throughout the summer. Height: 60cm (24″). Spread: 45cm (18″). Grow penstemon in a sunny or semi shaded position on fertile, well drained soil. Penstemons can tolerate dry soils once established but dislike heavy soils that are particularly cold and wet in winter. Improve heavy soils by adding plenty of coarse grit prior to planting.
