Tall Delphinium 'Sir Galahad' will create an abundance of purest white flowers, towering over compact, dark green leaves. For the best results protect the young foliage against slug-damage in spring and stake the slender stems well before the flowers appear. Plant to the back of the mixed border in a sunny position.
