Into the house again, rang a local carpet cleaner and he had a free slot, so I have clean carpets and a new friend. Took photos of the garden until the batteries ran out, and found a very odd thing. I knew what it was, after a moment, but had not expected to find it in a house with children. The rest of the garden did not suggest a plantsman had lived there. Datura stramonium, jimsonweed. What am I going to do with it? I've heard of places it grows wild, and used to look for it. And now I've got one.
