If you are serious about wanting a more tree like appearance, you have to provide this plant with way more light. Over the course of three weeks or so, gradually introduce it to more and more light. Ultimately it should be getting full sun for a minimum of half a day, but would even be better all day. You plant is currently etiolated (severely lacking light) which is why it looks so stretched out and the leaves are elongated. Pruning it now will only result in more of the same, unhealthy growth. The other thing the plant needs to get thicker stems is time. Not a year, not two years, but many years. In maybe five years you could expect to have a plant that doesn't look like a cutting anymore, assuming you start giving it an appropriate amount of light. When properly grown, the stems will be much thicker and the plant will generally look much more substantial. Despite the fact I've recommended against pruning at this point, no one ever wants to do things the patient way, so here are some quick tips about pruning Jades. Always prune just above a leaf node. The stem will die back to the node, so there is no reason to leave any more than necessary. Jades will almost always branch at the node you just pruned above. So, if you want it to branch in a particular spot, prune just above that node. You can prune as little or as much as you want. You could prune all the way down to the soil, and as long as the plant had some roots to begin with, and is kept warm, it will produce new leaves and go right back to growing. Spring and early summer are the best time to prune. That second plant is "Elephant's Food," Portulacaria afra. Everything I said for the Jade goes for that plant too. Finally, welcome to GardenWeb!

Rebutia muscula? Probably way off, I don't know much about cacti. It's just a guess from a quick Google search.

Following your suggestion I did some research using the Genus and species. I found a photo that looks nearly identical to it, so I think it is Ipomoea carnea ssp fistulosa. A very good educated guess on your part. Thank you.

poly, That's because they have a tendency to revert to their non-coppery/bronze colours in winter when there is less sun. As I mentioned previously, there is some toxicity, but I don't think it's fatal unless ingested in large quantities. OTOH, the Kalanchoe's relatice, the Tylecodon, is very toxic - lots of farmers in South Africa uproot them so that livestock won't eat them. It's recommended that human contact with them (such as in repotting) be limited, with some species of Tyls having much more toxin than others. Still, they're great plants - just handle with care.
