I grow these in my driveway garden,which is a little strip of dirt between the driveway and chainlink fence. They do not ramble,and they do not need staking like a tomato plant.Remind me of small bush bean plants.A few inches apart and they did well for me. I can't find a pic of the plant,but I did post the berries on my page:
I planted tomatillos with the ground cherried too!
I let them vine on the ground. They do ramble a bit. If you train them up, they'll be easier to find, but I'm too lazy for that.

I plant mine near tomatillos too, since they always take up more room than I think they will. They grow like tomatillos but don't get nearly as big. At least mine don't. I don't train them up but let them go where they want. The heavy branchs (stalks?) do bend down, hit the ground and then grow little roots. I'm traveling a lot this summer (gone for 8 straight weeks) and only planted things that will be consumed by early July, so ground cherries were out. I'll miss those little berries!

I've just let mine ramble, too. In my experience, they don't get huge - they maybe cover a square foot or two of space. I'm in a short-season area (zone 4), though, so maybe in a warmer area they'd have time to get larger.
