seemit - oldgraymare also asked this question on the Name that Plant Forum. Lisanti07028 was simply referring her/him back to his/her own duplicate question. It was answered 6 days ago and ogm responded with thanks. This is the kind of thing that happens when people post on more than one Forum. People following the thread on the 'wrong' forum don't see the outcome. The plant is Hibiscus trionum.

The plant is Euphorbia marginata. Snow on the Mountain is a cute name but it, like many common names, is also applied to several other plants. Common names are often descriptive and culturally interesting but if you are discussing plants with other gardeners or want to order/research them the botanical name is important. For example, if you talked to a Brit gardener about Snow on the Mountain they would be imagining Cerastium tomentosum.

I love these! I have some in my yard and one taking off in the house now:). They do self propagate like crazy, but if yours is potted, you should have no problem controlling that.

Agree, it looks like Aloe ciliaris. Here's is my plant almost 4 years ago. You can see how the leaves connect to the stem. It's one of the climbing Aloes. I planted mine in the ground. This is the same plant last summer. I haven't done anything to it and it has spread. I think I could have picked a better spot for it! And I think I'll prune some and start a plant in my backyard under a big Yucca 'tree'.
