Delphiniums are the stars of the early summer border. Plants form a low mound of deeply-cut green leaves, bearing tall spikes of satiny flowers. Removing faded spikes at the base will encourage repeat blooming in fall.
Cut back hard to encourage fresh foliage. Use a high phosphorous fertilizer each year, in early spring.
Hot, humid summers can bring on potential mildew.
CAUTION: Harmful if eaten.
