Last year I had yellow black-eyed Susan vines. A friend gave them to me. They did all right, but I didn't like the red of the angel-wing begonias with the bright yellow of the vines. I liked it that they trailed down, but the colors weren't wonderful.
This year I ordered white and pink or red ones (don't remember which). This is the first bloom. I hope they seed as readily as the yellow ones.
