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

36–48".

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 elatum

Also known as

Candle larkspur.
