Percival Delphinium Seeds

Delphinium ‘Pacific Giant Series – Percival’ Seeds
(Delphinium cultorum)

Delphinium ‘Percival’ from the Pacific Giant Series produces tall spikes of soft lavender-blue flowers with bright white centers, often called “bee” markings. The blooms are densely packed along upright stems, creating a full and eye-catching display. Plants typically grow 4–6 feet tall and bloom in early to mid-summer.

This variety is known for its classic delphinium form, strong stems, and reliable performance. It attracts bees, butterflies, and other pollinators and also makes an excellent cut flower.
