There are three in total. They technically belong to Hogwarts, but since there’s only a few of us, I’ve taken over the care for the greenhouses with Richie. There are various plants in them. I’ve left more advanced ones or ones likely to cause some harm without proper knowledge of them in a greenhouse with a spell to keep most people out. I don’t want someone to wander in and hurt themselves. Especially with the Mandrakes.
