How to Grow Hyacinth Bean Vine:

Hyacinth Bean Vine is easy to grow. Grow in full sun. Plants prefer a rich, well draining soils to fuel their fast, season long growth. Mix a healthy dose of compost into the soil prior to planting.

Plants need a lot of water and nutrients. While they like lots of water, they do not like wet soil. Keep soil moist, not wet. Add fertilizer when planting and every month during the season. Use a high phosphorous formula just before the first blooming period.

Plants will begin to bloom in summer, and continue to do so into the fall. After the flowers bloom, purple pods will begin to form. The bean pods grow up to three inches long. The raw beans are poisonous. Keep away from children and pets. Boiling beans for a long period cooks out the poison, and makes the bean edible.

Hyacinth bean vines are annuals. They are very susceptible to frost. Flowers may bloom all the way up to the first.frost.

Hyacinth Bean Vine plants are good "re-seeders". If the pods are allowed to open and pour out their beans, you will find many new plants next year. Do not disturb the soil until seedlings have begun to grow. Thinning will almost certainly be needed.
