I got the little guy as a gift, with one branch. Been keeping it for years and really haven’t paid too much attention to it until the past year or so.
With the Portulacaria, same plant, different common names being used. As long as you have the small foliage variety, you’re good.
If you’re doing Portulacaria, you absolutely need to read this by Adam Lavigne. He’s in Florida, and I’ve learned a lot about Portulacaria from him.
Also check out the Phoenix Club’s resources page. They have a list of plants and rate them on how well they do in the area. The list is a little old, but it’s a great place to start from.
And hit me up with a message anytime. I’m always up for talking shop with someone who deals with the same weather that I do.
