The hyacinth bean vine has been around for thousands of years, and today there are many cultivars commonly found and grown all over the world. Keep reading to learn about the different cultivars of the hyacinth bean, as well as the plant’s history!


History of the Hyacinth Bean Vine

Although the official origins of the hyacinth bean vine are uncertain, it is widely believed that this plant originated in Eastern or Southern Africa. Some accounts even report the hyacinth bean vine growing in India as early as 2000 BC.

The plant is commonly featured in many Asian and African dishes. Typical uses for the hyacinth bean vine include Indian curries, Vietnamese soups, and a Kenyan dish that involves blending the beans with sweet bananas.

However, if you are looking to cook with the hyacinth bean vine, take precautions. It’s important to note that the mature dried beans are toxic without proper preparation. High levels of cyanogenic glucosides can cause severe illness in both people and animals.

To rid the hyacinth bean vine of its toxins, the mature beans must be soaked and boiled for a considerable time, with the water being changed at least twice. An undesirable odor may be present while cooking the beans.

Always err on the side of caution when consuming the hyacinth bean vine. It’s best to use the hyacinth bean vine for decor rather than eating. Immature shoots and other parts of the plant such as the flowers and leaves are a safe and edible option.

The Highworth variety comes from Southern India, boasting purple flowers and black seeds. The Rongai hyacinth bean vine originated in Kenya, and displays white flowers and light brown seeds.

Highworth vines mature quickly, developing flowers must faster than the late-maturing Rongai vines.

Because they’re not common varieties, Highworth and Rongai hyacinth bean seeds are tricky to come by. We recommend checking the beans seed inventory at Hoss Tools to see if they add hyacinth beans to their selection.
