- TX L.Rated 5 out of 5 stars8/12/25Beautiful vining plant for trellis
Second year growing these vines. All seeds germinated, but always double plant just in case. These take a bit of time to grow out before they flower, but are stunning by late summer.

These did great. All sprouted. Two died after heat wave. Going strong - about 6-8” tall each

I love this plant. I have vines growing in two different locations. They are just now starting to flower, and I am anxiously awaiting the pods to form with bean seeds. These vines I have are from saved seeds from last year.

I plant lablab beans (hyacinth beans) for humans and hummingbirds. The cooked beans are a delicious and tradtional African vegetable (despite the warning not to eat in the site), and the flowers attract hummers in late summer and fall. The seeds hate the cold. Don't sow until nights are above 60'F.
