There is an article online about String of Pearls which includes this photo. I was wondering what the other plant growing with it is, but that was not included in the article. Thanks!
Looks like a type of Sedum (sp?)
Ok! Will research more. Found something close looking called Sedum glaucophyllum but not completely sure.
Hopefully some others will look in soon and maybe be able to help narrow it down. :-)
Many sedums will have the same effect, as well as intergeneric sedeveria hybrid.
