Purple Bell Vine Flower Seeds

About Purple Bell Vine Flower Seeds

Purple Bell Vine Flower Seeds grow in full sun, partial shade positions. Expect 120 inches at maturity. Flowering runs late spring through fall. 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. Start seed indoors and move the seedlings out once the danger of frost has passed. Hardy in zones 9 to 12 — your local frost dates decide the exact week.

Where to plant

Choose a site in full sun, partial shade. Water needs are high 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 9 to 12 inches between plants so air can move between them. Plan for 120 inches of growth when you place them in a bed or border.

How to plant

Sow 1/16 inch deep, spaced 9 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. Indoor starts do best in warmth and bright light; harden the seedlings off over a week before planting out.

How to care

Keep watering high, at the base of the plant rather than over the leaves. In zones 9 to 12 these come back each year: let the foliage die down naturally after flowering, since that is what feeds next season's growth. Flowers appear late spring through fall; cutting or deadheading regularly keeps more coming.
