Ours is setting buds again right now. It's grown outdoors in Southern California and needs bright light in order to flower. They're easy to grow, but you have to be careful not to over water it. Let the surface soil dry out between waterings. But I also have fans moving air all around the greenhouse, which we didn't have then.
Air movement makes a big difference.
Highly popular ivy topiaries are most often victims of spider mites in private homes. It's like a mite magnet. We asked two Sacramento houseplants for some of their favorites. Plus, people know they can put them outdoors on the porch instead of keeping them in the house all the time. In fact, at the recent home and garden show at Cal Expo, we had to stop people from pinching the blossoms.
