Pacific Giant Blue Bird delphinium produces gorgeous medium-blue flowers, with white bees.
Huge 3 in. double summer flowers are excellent for cutting. When first flower spike is removed immediately after bloom, additional spikes quickly form. Plants grow 4-7 ft. tall, need staking to protect heavy flower spikes from the wind. The palmate-shaped leaves are large.
Pacific Giant Blue Bird delphinium is a dramatic plant for the cottage garden or the back of borders. Winter hardy to zone 3.
