Growing Information

Days to germination

About 21–28 days at 21–24°C (70–75°F). Chill the seed in the refrigerator for 5 days before sowing; light helps. Outdoors, the soil must be above about 18°C (65°F).

Starting indoors

Recommended. Sow 8–10 weeks ahead of your last frost, barely covering the seed. Move seedlings to cell packs or pots at the first true leaves, and plant out once the last frost has passed.

Direct sowing

Once the soil reaches about 18°C (65°F), sow groups of 3–4 seeds and thin to one plant at the true-leaf stage.

Plant spacing

10–15".

Soil

Humus-rich, free-draining soil.

Light

Part shade; full sun where summers are cool and plants are kept watered.

Winter

In cold climates, mulch after the first frost so freeze-thaw cycles do not heave plants out.

Harvest

Cut when half the flowers on a stem are open.

Uses

Cut flowers, beds and borders.

Hardiness

Zones 3–9.

Plant height

24–38".

Packet

50 seeds.
