I wasn't aware of the Black-eyed Susan vine until this year. I got a few little plants from a neighbor and put them in my hanging baskets. They aren't as striking as the angelwing begonias, but they make a really nice addition. The yellow color of the blooms is nice as it twines around the other things in the flowerboxes. I looked at Parks Seed and found that there are various colors available. I'm going to get several seed packets for next year.
I'm attaching a link so you can see other uses to make of this amazing vine.
It may be necessary to copy and paste to get the pictures.
