Just lost a 6-year old Aureum in northern Middlesex county in Massachusetts. Bummer.
Other than that it was gorgeous. In a warmer zone I would rate it a 5. This past winter was not extreme here. There were a couple of below zero small stretches -- maybe as low as -10F once. I call that average to above-average temps. We have had -22F some years.
Lovely small tree, doing well in Owatonna MN.
