Incredible vine!!! Actually I planted two separated varieties, the ruby moon and the white version. Although I am lover of white flower the purple plant are the best. I transplanted early this spring and transplanted in mid-spring. I planted several plants great part of which were able to fully develop.The plant grow slow during spring but at the beginning of the summer it really speed up!!! Beautiful the foliage, beautiful the bloom, beautiful the see pod. Very prolific, drought resistant, disease resistant...
I really cannot understand why is not that popular, if you have a fence or a trellis I strongly suggest to have one.
Anybody interested to this vine can contact me for having some free seed!!

Information compliments of Botanical Interests, Inc. ( "Annual. Blooms in summer. 6' to 20' vine. Full sun. Purple stems with dark green leaves and purple to white flower clusters, followed by eye-catching velvety purple bean pods. Makes an attractive fast growing screen. This exotic tropical looking vine can be grown up arbors, trellises, fences, in hanging baskets, or as a groundcover. It is used as an important forage crop in the tropics. The immature bean pods are edible, but probably not as good tasting as many other garden beans. The purple color will turn green when cooked. Mature bean seeds may be eaten, but they must be boiled and drained at least twice to discard the toxic cyanogenic glucosides. We do not recommend eating them. The common name is misleading, as Hyacinth Beans are not true beans. But, like beans, they are a member of the pea family. The Hyacinth Bean Vine requires well-drained soil to thrive and is much more drought tolerant than other bean varieties. OUTDOORS: Sow in spring after average last day of frost. (Recommended) INDOORS: Sow 6-8 weeks before last spring frost. Difficult to transplant - use extreme care (such as pulp pots) to avoid disturbing roots. SPECIAL GERMINATION INSTRUCTIONS: Soak seeds in water for 24 hours before planting."

Easy and fast to grow, especially when the weather warms up in spring. May as well direct sow, imo.

I actually find this to be fairly drought tolerant, especially compared to other annual vines I've grown from seed in the past.

Gorgeous flowers and red pods. A lot of plant per seed planted, and a lot of seeds generated from only one plant. It didn't generate pods for quite a while (early blooms just fell off), but once it decided to generate seed pods, there were lots. Flowers came in late summer, so it was a nice addition of color when so much else was done for the season. (Phoenix, Arizona)
