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. This selection has stately, pure-white petals. Removing faded spikes at the base will encourage repeat blooming in fall. In hot, humid summer regions, plants do not usually last more than 2 to 3 years. Plants are often attacked by mildew in mid summer; simply cut back hard to encourage fresh foliage. Use a high phosphorous fertilizer each year, in early spring. Will require staking early in the season. CAUTION: Harmful if eaten.
