About Lupine Flower Seeds
Lupine Flower Seeds grow in full sun, partial shade positions. The figures below are the ones on the packets in this group; each product page carries the exact numbers for that variety.
When to plant
Plant in fall, spring. Seed can be started indoors ahead of the season or sown straight into prepared ground once it has warmed. Soaking or nicking the seed coat before sowing speeds up and evens out germination. Hardy in zones 3 to 10 — your local frost dates decide the exact week.
Where to plant
Choose a site in full sun, partial shade. Water needs are average once the plants are established. Free-draining soil matters more than rich soil; seed sown into ground that stays wet rots before it germinates. Allow 12 to 14 inches between plants so air can move between them.
How to plant
Sow 1/2 inch or 1/8 inch deep, spaced 12 to 14 inches apart. Water gently to settle the soil, then keep the surface evenly moist until seedlings or shoots appear. Indoor starts do best in warmth and bright light; harden the seedlings off over a week before planting out.
How to care
Keep watering average, at the base of the plant rather than over the leaves. In zones 3 to 10 these come back each year: let the foliage die down naturally after flowering, since that is what feeds next season's growth.
