loribee2 and pippimac - thanks for looking and for your feedback! Most people (here on gardenweb and readers of my blog) seem to be in agreement that I have the weedy/wild variety, which according to some people can be poisonous. Fortunately, I have felt zero ill-effects after eating these berries today. Perhaps I didn't eat enough of them, or maybe the berries weren't poisonous after all. I have read documents that argue on both sides of poisonous/non-poisonous nature of the Solanum nigrum species.

It's impossible to say for certain what succulent it is, because of the way it is stretching for sunlight (etiolated). It just doesn't look like itself at the moment! Probably some sort of Echeveria or Sempervivum (also known as hen and chickens). Introduce it gradually to more light (over the course of a week or two); it will be happier outdoors as long as the weather doesn't get too close to freezing -- or too wet. In very cold weather, you should bring it inside: but place it next to a south-facing window. Ask on GW's Cacti & Succulents forum about how to repot it in a quick-draining mix so it will be healthier.

Here's what I'm doing, based on reading at Building Science.com and the architect -- Fiber cement planks furring house wrap, taped XPS @ 2" shiplapped (R10) 2x6 @ 24" o.c. OVE framing damp cellulose cavityfill (R19) sealed plates/sills & penetrations; foamed rims to R10 Sealed drywall latex paint AT the corners I'll use let-in 1x4 to provide shear walls Whether this will suit your purposes or not depends largely on your climate -- I'm in north Georgia so it is mixed-humid here. If you're in FL or AZ or MN or on the coast of OR makes a big difference in what will work best for your situation. Interesting reading at BuildingScience.com, as I said. Best wishes, JWilson

These are in Heritage Park and I'm guessing they take a dim view of people who pull their weeds. I think I just found out that it is Solanum Carolinense or horse-nettle.
