I thought it was odd that 'Diva' would have been grown in a green house, but I see it is actually
'Diva's Choice' a much later cultivar: Heemskerk 2012, Tet., Dor.
So that makes it much more likely to have been grown in a green house. I just received some plants form Floyd Cove a week ago and two of them have scapes already.
I was just not thinking it would be warm enough in Arkansas for them, but I don't know, hope a freeze doesn't zap them. I think it is often advised to remove early scapes like that, but I know it is hard to do.
