I have a houseplant in the greenhouse I was given. a clivia. It is next to the back of the potting tray and the idea was to bring it in and have it bloom. Plan on hold; whilst working at the potting tray I kept getting 'buzzed' by a small bee, then I spotted it vanishing into a hole in the earth at the edge of the clivia pot. It's pretty regular, and seems to have got a bit used to me. When the door is open it flies straight in through it, but has problems getting out, flying around the panes. It is an old and leaky greenhouse though so it gets out.
