Hi,
I live in the Midwest and just bought a Montrose Apricot tree. This will be the first apricot tree I've ever planted. I was told it's very cold hardy by the nursery I purchased it from. There are even these type of trees planted near the Canadian border in Idaho from what I've found out. I hope to have a crop on it this summer since fruit is ready to eat in mid-july. The standard variety grows 15-25 feet tall. I will have to let you know how the fruit tastes and the pit tastes after my first crop production. Hope some of this info helps.
