Delphinium Black Knight
Product ref: P10143
Majestic spires of semi-double, deep purple flowers with black eyes in June and July. These dark-eyed delphiniums look great planted in bold clumps towards the back of a well-drained, sunny border. For the best results protect the young foliage against slug-damage in spring and stake the slender stems well before the flowers appear. Supplied in 2-3 litre containers.
