This hardy plant can survive low temperatures.
This plant likes partial sun. Some grow it indoors, and if you choose to do so, be sure it gets six or more hours of sunlight on a bright windowsill each day. Outdoors, to spread and look its best, it needs only occasional watering... truly low-maintenance. Just be sure its soil drains well, and also be sure its top layers of soil have dried before more water is applied. Fertilize with a highly diluted liquid fertilizer every couple of weeks for the best flowers. You may want to snip spent blooms to keep the plant tidy.
