Belladonna Mix Delphinium Seed

Item #HSC-DEL-001-PKT

A hardy Belladonna delphinium mix.

This Belladonna mix flowers in its first year, with well-branched plants carrying spikes in a blend of deep blue, turquoise and white.

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.

Growing guide

From seed to harvest

Start early and cool

Sow 10–16 weeks ahead; grow seedlings on at 50–55°F.

Support 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.

Scientific name

Delphinium x belladonna
