SongofJoy said:They do bloom but sometimes not prolifically compared to other plants. It has been my experience that they like well-drained soil and full sun. They will tolerate partial shade but don't usually do their best in those conditions. Water potted plants when soil feels dry. They also like a balanced fertilizer. Relocating them may solve your problem although everyone's growing conditions are different.
