Wallflower Flower Seeds

About Wallflower Flower Seeds

Wallflower Flower Seeds grow in full sun, partial shade positions. Expect 16 to 24 inches or up to 16 inches at maturity. Flowering runs spring. 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. Sow directly where the plants are to grow; this variety does not transplant happily. Hardy in zones 3 to 9 — your local frost dates decide the exact week.

Where to plant

Choose a site in full sun, partial shade. Water needs are low 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 10 to 12 inches between plants so air can move between them. Plan for 16 to 24 inches or up to 16 inches of growth when you place them in a bed or border.

How to plant

Sow 1/16 inch deep, spaced 10 to 12 inches apart. This seed needs light to germinate, so press it onto the surface and firm it in rather than burying it. Water gently to settle the soil, then keep the surface evenly moist until seedlings or shoots appear.

How to care

Keep watering low, at the base of the plant rather than over the leaves. In zones 3 to 9 these come back each year: let the foliage die down naturally after flowering, since that is what feeds next season's growth. Flowers appear spring; cutting or deadheading regularly keeps more coming.
