About Hyacinth Bean Flower Seeds
Hyacinth Bean Flower Seeds grow in full sun positions. Expect 10 to 20 feet or 10 to 20 ft at maturity. Flowering runs summer 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 fall, spring. Sow directly where the plants are to grow; this variety does not transplant happily. Soaking or nicking the seed coat before sowing speeds up and evens out germination. Hardy in zones 10 to 12 — your local frost dates decide the exact week.
Where to plant
Choose a site in full sun. 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 6 inches between plants so air can move between them. Plan for 10 to 20 feet or 10 to 20 ft of growth when you place them in a bed or border.
How to plant
Sow 3/4 inch deep, spaced 6 inches apart. Water gently to settle the soil, then keep the surface evenly moist until seedlings or shoots appear.
How to care
Keep watering average, at the base of the plant rather than over the leaves. In zones 10 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 summer through fall; cutting or deadheading regularly keeps more coming.
