Succulent Plant, Portulacaria Afra 'Elephant Bush/Food'
This beautiful succulent likes the soil to be dry for no longer than 1-2 days. This is a trailing/draping form, not the upright bushy one.
I put a small start of this outside last late spring as a personal plant and test of its hardiness. I learned that this one can handle some summer Arizona sun if watered regularly (every third day)--perhaps two hours of late afternoon sun or any amount of morning sun. Some say no, but I consider it a good (reasonably fast) grower assuming you're giving it enough light, fertilizer, and water.
