Thanks for the answer!
I also thought about the possibility it could be some crabapple dna manifesting - if that is the case, I hope it gets the leaves and NOT the taste!
I bought the seeds from treeseedsplus on ebay. It is supposed to be seeds from the cultivar Red Delicious. My plan is to plant every plant that survives along my fields - maybe. One of the trees produce a wonderfully tasting tree - I'll see in 10-15 years
I bought seeds from a couple of other cultivars too, Fuji and Antonovka. The red delicious was first to germinate, followed by Fuji. But from the Antonovka seeds - which is supposed to be cold hardy - there hasn't been a single seed germinating. I think it is the eternal cold weather this year! It NEVER ENDS!!! We have had snow now for the last week, every day, in May - usually we see the last snow in March... I hope this isn't the trend
