Can a registered dormant x registered dormant cross produce evergreen seedlings, semi-evergreens and/or dormants. I would say yes, but it might produce more dormant seedlings than other types. How well those seedlings grow in specific locations might depend more on where their ancestors were hybridized than their registered foliage type. (We do agree)
Here the hard dormants will go below the surface during the winter and not resurface until early spring if they resurface at all, (these preform very poor here), the other dormants will act like semi-evergreens and have about two to three inch's of foliage above ground all winter,(most of these do some what better and a few do really well) Semi-evergreens will have four to five inch's of foliage during the winter(do great here, as well as evergreens).
