Cape Gooseberry (Physalis peruviana) is also known as Incaberry, goldenberry and Pichuberry and a few other common names.
I find germination to be a bit hit and miss, I planted seeds that didn't germinate, then a few weeks later I replanted seed from the same packet and they all germinated. They grew very slowly at the start and felt like they would never flower. Once they started to produce fruit it was very productive over a long period of time.
