These plants, and other non-hardy succulents look great in our front courtyard all summer, and they're easy to care for because they don't need much watering.
However, it's getting cold - last night it was only 5 degrees C (41F) - and today we must move them into the greenhouse, where they'll spend the next six weeks or so before we move them to the basement (because we don't heat the greenhouse in the winter). Once inside, they overwinter under a big mercury vapor light.
I'm lucky that my husband doesn't mind looking after them. I take care of so many plants in the summer that I don't even want to look at them in the winter.
