I grow a lot of this...also common name Persian shield It can grow 3-5 ft. tall and spread 2-3 ft. Will grow in sun or part shade. Can be used as a ground cover. Great speciman plant.

Wow, thanks! You guys are good! I found this link to rhipsalis dissimilis, and the pictures seem to be a perfect match -- especially the green flower "buds." Here is a link that might be useful: R. dissimilis

Make sure you pull it up before it goes to seed. They are all over my yard but at least are easy to pull.

Mary, before you move them let me tell you where mine grow. I have a few that only get a couple hours of morning sun, some that are actually my neighbors and have "crawled" under the wood fence and are thriving with about 4 hours of sun, a few more planted under ligustrums that get no sun. I think it's hard to lose with this one, lol!
