Size and Method of Climbing
Hyacinth bean is an annual vine, but it is still capable of growing 12 to 15 feet in a season. It is a twining vine. Twining vines climb by twisting their stems or leaf stalks around a support. This type of vine grows well on trellises, arbors, wires or chain-link fences.
Grow in full sun and moist, well-drained soils. Hyacinth bean is easily grown from seed. Start indoors 2 to 3 weeks before the last frost and transplant outside once the danger of frost has passed.
