I have grown this plant as a houseplant for several years because it is not hardy in my zone. It is an easy plant to keep, and it rewards me with beautiful flowers in late winter when little else is blooming.
I grow it in a one-gallon pot and I re-pot it every 3rd year.

The common name of Apostle Plant is used because of the belief that it will not bloom until it has grown 12 leaves.
