As I'm just into my 4th year of backyard hybridization I thank all for the information. I cold stratify all my seeds and don't start indoor planting until January or February. If I may asked something that may be related to temperature affecting a plant of mine. Four years ago I purchased Undefinable (listed as evergreen) planted in the ground it didn't grow a great deal but did always produce a few blooms. Reading in this forum a member said they dig up their Undefinable and store it in an unheated garage. So I tried this last year late fall . The plant stayed green all winter and I brought it out after danger of heavy frost .The plant grew quite well however it didn't produce any flowering scapes . So my ? is did it require complete dormancy? Thanks you
