Delphinium ‘King Arthur’


Pacific Giant Delphinium

USDA Zone: 2-9

Plant number: 1.175.400


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 rich, deep royal-violet petals, with a white centre, or “bee”. 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. CAUTION: Harmful if eaten.
