We have grown this in our stock beds for ten years or more and it has consistently made a terrific display of autumn colour turning crimson, pink and lemon during April.
One of my favourite Penstemon with the loveliest blue-mauve white throated flowers beautifully poised on long pedicels. Flowering as it does from late spring until winter it has been a mainstay of our double borders for many years.
Deep violet-purple tubular flowers are carried on 90cm tall stems from late spring until late autumn. Glossy, dark green foliage adds to the affect. Plant in any sunny or lightly shaded spot. Removing spent flower stems will keep the display looking fresh.
Like all of these hybrid Penstemon this variety is very tough and drought tolerant. This clone is one of the tallest of its kind growing up to 120cm. The top third of this carries charming lilac pink, white-throated tubular flowers. 120cm x 90cm.
This Penstemon has bright reddish-purple flowers over glossy leaves, from spring until winter. It is an evergreen plant, needing only a winter tidy up, and a sunny spot. 70cm x 70cm.
This is one of the most famous of all the Penstemon. Vita Sackville-West had it growing at Sissinghurst for many years. It has soft green, amethyst and blue, narrowly tubular flowers. 70cm x 60cm.
Another superb white penstemon with all the virtues and showing just the most delicate blush of pink as the flower ripens. One of the best white flowering perennials for use in a border.
