Container Grown Hyacinth Bean
As with all potted vines, container-grown hyacinth bean vines need something to climb on. In their native tropics, where they can grow for several years, they often reach over 30 feet (9 m.) in length. Hyacinth bean vines aren’t at all frost tolerant though, so, in most places, they’re grown as annuals. Even in a single growing season, however, they can get as long as 15 feet (5 m.). This means they need something tall and strong to climb. Growing hyacinth beans in pots means that you can place them where you want. Place your container near the bottom of a railing or fence and let it climb away. Alternatively, plant your beans in a hanging pot and let the vines trail down to the ground in a spectacular cascade.
Growing Hyacinth Beans in Pots
Hyacinth bean vines are very forgiving when it comes to growing requirements. They will do well in soil that is poor and both slightly alkaline and acidic. Any standard potting medium should be more than enough. They do require well-drained soil, so make sure your container has plenty of drainage holes. They perform best in full sun, but they can take some shade. You can sow the beans outdoors after the last chance of frost or start them inside several weeks earlier. The beans themselves are edible, but toxic if eaten raw. Always cook your hyacinth beans thoroughly before eating them.
