Thanks! I think I’m going to trudge ahead with Harrison.
I had questioned it initially because I had it in Virginia and I thought my season may not be long enough for it, but it seems someone close to me (4a) has had success growing it! Cummins says October harvest in New York too, but thats very general, upstate New York has so many hardiness zones.
When I tasted it, it reminded me of a spicer Golden Russet of Western New York, which is one of my favorites of all time, but its a massive tree plus a tip bearer and want nothing to do with that.
