Romantic and statuesque, Delphinium ‘Guinevere’ from the Pacific Giants series produces towering spires of soft lavender-pink blooms with delicate white bees at their centres.

A classic favourite for structure and height, 'Guinevere' brings a soft, dreamy presence to early summer gardens.
Best for: Cottage garden borders, tall statement stems in bouquets, soft pastel arrangements, and romantic perennial plantings.
CAUTION - all parts of this plant are poisonous including the seeds so take care when handling.

| Growing Tips |
Plant in full sun to part shade, in deep, fertile, well-drained soil. Needs staking or support to hold tall flower spikes upright. Deadhead or cut back after flowering to encourage a second flush.
