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.
