Audrey, Sorry I missed your question. The seedlings are 22 mths. Approx.
Crystalview, There are what they call Dwarf & those called Mini-Size. One has smaller blooms I believe.
I would pot up at same level Rinoa had it at. These do not grow as quickly as other obesum's.
The pots I have these in are 4" pots w a depth of 3 1/2".
