Canadian Hardy Apple Trees

Most apples won't reliable fruit here with late spring frosts that we get into June and sometimes July. Apples are said to need only about 10% of their blossoms to get pollinated and not get frozen, so if the tree blooms really late or over a long period it has a greater chance of having some blossoms pass through their most critical time without freezing.

There are a number of super hardy apple varieties that will produce fruit in the most inhospitable climates. Here are a few interesting apple links if you have late spring frosts that typically kill your apple blossoms. Some of the trees are hardy even down to zone 2 in case you get those brutally cold winters.

Clair's Cultivations - great list of good producers in Fairbanks, Alaska at the end of the page

Most of the Canadian trees are only available as scionwood from a few companies or the USDA Germplasm Unit.

One tree that always produced in Southeastern Idaho in zone 3b was Wealthy. Wealthy is a great tree that is available in the U.S. Honeycrisp is also supposedly a good producer in cold harsh climates, but I haven't tried growing that one yet.
Red Wealthy

I'm growing Goodland, Northern Spy, Morden 360, Tolman Sweet, Norda (possibly the same as Norkent), Ginger Gold, Red Wealthy, Spitzenberg, and Cortland. I am guessing that the last two will not fruit every year due to frosts, although they still need a few more years to start fruiting before I find out for sure.
