Lin: This avatar photo I have is Blue Silk. It is a knock-out flowering vine! You have some nice looking vines by the looks of them in your photos.
Chris: It suddenly got very warm here in Delaware too. I am sure the weather change will spur the vines on to make a few more flowers. I am hoping the warm weather will last long enough for the seeds to fully develop on the vines.
Tee: thanks for the comment! Try growing an Ipomoea purpurea, they are fairly easy to grow and flower readily indoors.
