Bred in the 1920’s and still one of the best of its kind, Penstemon ‘Garnet’ has been a stalwart of our double flower borders for at least ten years. 60cm tall stems clothed with narrow glossy dark green leaves carry dozens of rich magenta pink flowers from spring until winter. We tidy the plants up in winter by trimming to about 40cm. During late spring when new shoots grow from the base we cut all of the spent previous seasons wood to the ground. 60cm x 60cm. Sun.
