Pacific Giant Mix delphiniums include flowers in shades of rosy lilac, light blue, mid blue, lavender blue, lavender pink, royal violet, dark violet and white. All blooms have dark or 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 Formula Mix delphiniums are dramatic plants for the cottage garden or the back of borders. Winter hardy to zone 3.
