Growing guide

From seed to harvest

Soak or nick seed

Soften the hard coat, then expect sprouts in 2–3 weeks at 65–75°F.

Protect the taproot

Use deep cells and transplant before roots crowd.

Cool summers suit it

Sun to part shade, 18–24" apart, slightly acidic soil.

Cut most of the spike open

About four-fifths of the florets showing color.

Growing Information

Days to germination

Usually 2–3 weeks at 65–75°F (18–24°C). Lupine seed has a hard coat: soak it overnight or nick it with a file before sowing to speed things up.

Starting indoors

Sow 4–8 weeks before planting out. Lupines grow a long taproot, so deep cells (such as 32- or deep 50-cell trays) give the best plants; standard 50- or 72-cell trays work if you transplant on time. Roots that hit the bottom of a cell set the plant back for good. Keep one seedling per cell once true leaves show, harden off and plant out; seedlings shrug off a light frost.

Direct sowing

Cover the seed with about 1/4" of soil; it sprouts best in the dark.

Light

Full sun to part shade.

Climate

Lupines do best where summers stay cool.

Plant spacing

18–24".

Hardiness

Perennial in Zones 4–8.

Harvest

Cut when about four-fifths of the florets on the spike have opened.

Soil

Moist ground that drains freely. A pH of 5.5–7.0 works, and slightly acidic soil is best.

Uses

Cut flowers, borders, mass plantings, cottage gardens and meadows.

Caution

Every part of the plant, seed included, is poisonous if eaten. Keep children and pets away from it.
