What do you believe your lowest temperature will be in the coming years?

The Tri Clem Yuz might price to be very hardy if I had to take a wild guess. Most trifoliate hybrids are hardy to something between 0 F and 15 F depending on the variety, but they pretty much all have parents that are hardy only to twenty or the upper teens. This new one has Clem Yuz as a parent, and it's hardy to something around 10 F already. Combine that with trifoliate and the odds of getting something hardy to sub zero temperatures start getting decent. Not guaranteed, but possible.
Not being deciduous though will still be problematic for really pushing the hardiness. I'm not aware of any first gen trifoliate hybrids that are deciduous. Evergreen leaves can cause issues and extra stress on the plant in very cold weather, especially in dry, windy weather and if the soil freezes.
But regardless, this cross has the potential to be very, very hardy.
My 2¢ anyway. I'll be following the Mulberries YouTube channel for updates as time goes by.

In the past few years this area hasn't seen below 17°F or so. However in 2018 there was a low of 4°F. This feels like it will be a colder Winter than last year so I'm not sure what we will see, but likely at least below 20°F. I actually hope it goes a little lower to test some of these varieties early.

I agree, Tri-clem-yuz #1 has the most potential if it can survive. Tri-clem-yuz #2 probably won't taste good but so far it seems deciduous which is a good sign. They have good parents for flavor and hardiness so crossing my fingers #1 gets a good mix of both. The seeds originated from a Clem-yuz 2-2 fruit.
Thank you for your subscription!

Thank you everyone.
I agree with this, I've noticed many other people sharing my enthusiasm for selecting and breeding new varieties, and even looking to repeat the F2 Citrange Winter hardiness trials. On a large scale this could yield some very good results.
