My first time blooming seedlings have just begun and it is coinciding with the weather turning quite cool (in the 50s). Only 3 have opened so far but numbers 2 and 3 have keep their bloom for more than one day. In particular, I thought number 2 seemed to be opening two evenings prior to today; it opened fully yesterday and as of 2 pm today looked the same as the day before.
Does anyone know if this will mean they are extended bloomers or do I have to wait to see what they do in warmer temperatures before I make that judgement?
