Delphinium grandiflorum ‘Diamonds Blue’


Dwarf Delphinium

USDA Zone: 2-9

Plant number: 1.176.090


Very different from the traditional tall spiky Delphiniums, this strain forms a low, bushy mound of lacy green leaves. Plants bear loose sprays of single blooms all summer long, in a gorgeous electric blue shade featuring a purple spot on each petal. Ideal for containers, the rock garden and for edging the sunny border. Remove faded flower heads regularly to encourage repeat blooming. Although not a long-lived perennial, this will often self sow where happy. Said to be tolerant of hot, humid summer climates. Also known to do remarkably well in areas with short, cool summers. An outstanding cut flower. CAUTION: Harmful if eaten.
