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.

Grew Ruby Moon for the first time last year in the same big pots where I also grow Moonflowers. Those hyacinth beans grew to 15 feet high when they found something tall to climb on! They produced gorgeous flowers and interesting pods and have quickly become a "must have" from now on. I direct sowed them in the pots along with the Moons and they germinated well during early May in Northeast PA.
