Anchusa is usually grown as a perennial in the herbaceous border, but there is a dwarf annual species which is excellent for bedding or window boxes. The bushy plant bears branching stems which are covered with starry blue flowers in midsummer. The secrets of success are to dead-head regularly, keep well watered and spray against mildew if white spots appear.
