Perhaps Ipomoea sloteri

It's hard to tell from that picture

Hummingbird vine.. (slang)

cypress vine

It's cypress vine. I just learned about it two weeks ago. I found some growing wild yesterday and took cuttings and dug a small one up. It is in the Morning Glory family. It is an annual, but it will reseed readily from the seeds in the seed pods it grows. The hummingbirds love it!

I have the cuttings in water, but they won't root.
