Some good news I found for you..

' HEDELFINGER Continues to perform well in New York, Canada, and Europe. It has been around for more than 200 years and will be for a long time to come. It is a medium-large, firm-fleshed, high quality dark cherry that resists cracking. Productive. It has proven to be very winter hardy here in Western New York.'

So looks like you got a real bargain! Not sure how high it grows so might be worth checking up before planting as some varieties grow quite tall.
