Delphinium ‘Round Table’
Approx. 25 seeds.
A beautiful mixture of nine Pacific Hybrid varieties — Astolat, Black Knight, Blue Bird, Blue Jay, Camellaird, Galahad, King Arthur and Summer Skies. Together they produce tall, elegant spikes of double and semi‑double flowers in blues, purples and whites, each with bees ranging from white to deep, inky blue.
Delphiniums are a quintessential cottage‑garden favourite, loved for their tall spires, rich colours and classic summer presence. They come in a wide range of shades and forms, and benefit from pruning after flowering, often rewarding you with a second flush of blooms later in the season.
Perfect for borders and cutting gardens, these statuesque plants bring height, drama and movement to summer displays.
