A seed worth growing
Cliveden Beauty Delphinium Seed
About this variety
A hardy, airy sky-blue delphinium.
Cliveden Beauty is a hardy Belladonna type that flowers in its first year. Well-branched plants send up long, slender stems of lacy, sky-blue flowers, a much-loved shade and a light, open look in arrangements.
The stems are tall and can lean after a storm or a windy spell, so staking helps. Many growers treat it as an annual. Bees and butterflies visit the flowers. Perennial in Zones 3–7.
Plants grow 40–60" tall and flower about 130–135 days from sowing. Open-pollinated.

Quick Facts
Growing times vary with weather, soil and local conditions.
Growing guide
From seed to harvestSupport the spikes
Use netting or stakes; tall stems topple in wind and rain.
Feed lightly, often
Fertile, well-drained, slightly alkaline soil with regular light feeding.
Cut at a third open
Harvest when 1/4–1/3 of florets open; cut back for a second flush.
Growing Information
Days to germination
10–20 days at 65–70°F (18–21°C).
Transplanting
Start indoors 10–16 weeks before planting out, covering the seed lightly; direct sowing is not recommended. About 6–8 weeks after germination, move seedlings into larger cell packs or 3–4" pots and grow them cool, at 50–55°F (10–13°C), in a greenhouse or cold frame. Harden off and plant out after the last frost. Water at the base rather than overhead.
Greenhouse cut flowers
For a protected crop, set plugs into raised beds in August or September, run horizontal support netting 12–18" above the bed, keep the house below 60°F (16°C) with some heat, and feed with a balanced fertilizer.
Light
Full sun to part shade.
Plant height
40–60".
Plant spacing
12–18" when grown as a perennial; 12" when grown as an annual.
Hardiness
Zones 3–7. Plants are short-lived perennials and usually last about three seasons.
Harvest
Cut when a quarter to a third of the florets on the spike are open and put the stems straight into water. Cutting plants back right after the first flush often brings a second bloom in late summer and early fall.
Soil
Fertile, well-drained, slightly alkaline soil rich in organic matter. Feed lightly and often with a balanced fertilizer.
Uses
A classic cut flower and a backbone plant for perennial beds and borders.
