Here's mine in bloom in the greenhouse. It usually blooms in March. I had this in the house for years and it didn't bloom at all. Then the kids broke the pot roughhousing in the family room and I moved it into the greenhouse to repot. Repotted and decided to leave it there. I think it needs a spot of cold nights to bloom well because the following spring it was covered in these blooms. I was stunned and amazed.
