@JesseS I supplied that background info to Salt Spring after talking to Bill McKentley, former owner of Southmeadow Nursery. Milo gave scions of the apple (then named Linnwood) for evaluation to Prof. Elwyn Meader (of persimmon fame), Robert Kurle and Fred Ashworth of St. Lawrence Nurseries, all NAFEX luminaries. All gave it a two thumbs up.
I figured if those three gentlemen deemed the apple worthy of the name Milo Gibson, it was definitely worth grafting. John Bunker at Fedco raves about the apple. My grafts have not fruited yet.
Thanks for posting your tasting notes. Milo Gibson discovered, among other gems, Sunflower pawpaw variety growing in the wild in Kansas in 1970. He had a franken-tree in Oregon with over 100 apple varieties on it.
