About Vinca Flower Seeds

Vinca Flower Seeds grow in full sun, partial shade positions. Flowering runs summer. 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 spring. Seed can be started indoors ahead of the season or sown straight into prepared ground once it has warmed. Hardy in zones 1 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, 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.

How to plant

Sow 1/4 inch or 1/4inch deep. 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, low, at the base of the plant rather than over the leaves. Grown as an annual, so plan to sow again next season. Flowers appear summer; cutting or deadheading regularly keeps more coming.
