How long for 2s to be mature?
I imagine it takes a lot of energy to produce those large flowers, especially the enormous ones like Elsa Spath.
Elsa was one of my cheapies from Lowe's, most of my clems were purchased from Silver Star. I put Elsa in a little pot last year, then a 1 gallon, and then we planted her. She produced 2 flowers this year. I do not have the heart to cut off buds. The 2 flowers are huge and gorgeous.
I know everyone has different gardening conditions, of course. But assuming you water and feed, would it be another year or two before I really see the goods?
