I'm also in Manitoba (jsut south of Winnipeg, Z3), so I can tag on here:
Most everything I planted over the last two years survived the winter, but definitely some with winterkill, here's my list. All survived well unless noted:
Opal plum on mustang rootstock - took winterkill to snowline
Debbie's gold apricot
CHERRY (Sour, Pin)
APPLES - all grown as espaliers, 1st tier at 18", then 12" apart
PEARS - these had snow heaped on them up to 3-4' high. A few went above the snow line and had winter kill as noted.
Flemish Beauty - may have taken winterkill above snowline, BUT i think what actually killed it was high standing water. Both it and Pattern leafed out fully, then died down to much lower on the trunk. I think its because our yard has been oversaturated due to spring flooding and nonstop rain.
Patten - same damage as flemish beauty
Contender on Krymsk 86 - Severe winterkill above snowline, only 1 branch leafed out that was under the snow.
Harrow Diamond on Bailey - Flowered and pushing fruit!!!
Saturn Doughnut on Bailey - DEAD. failed to leaf out. Trunk passed the green-scratch test early in spring, but failed to develop any new buds and leaf out. Appears dead.
Transparent Yellow on B118
I'm looking for more peach seeds to try growing - if you have any to share, please let me know!!!
