A start of the plant was given to me by my friend Ursula a couple of years ago. I was a bit leery of it, to tell the truth, but I stuck it in a pot and basically just forgot about it for several months. That was in October. The next spring, there it was, hale and hearty. Obviously, the plant doesn't require much care.
In fact, in researching the plant's care later, I found that it thrives on having a cool, dry rest period in winter, so I had inadvertently given it exactly what it needed to flourish. In the growing season, it enjoys having full sun and moderate water, preferably in a well-drained soil (2 parts loam to 1 part sharp sand) with small pebbles mixed in for drainage. They thrive in pots and can withstand extreme heat. Sounds ideal for my garden!
