I planted an Autumn Blaze Maple at my home in Lakewood Co. It was around 8' tall when I had it planted. For 5-7 years it grew really fast and grew to 20-25 feet tall. It did suffer from iron deficiency. The leaves turned bright yellow in the fall, but never the deep red even with iron supplements. It was prone to sun scalding and the bark on the south side of the trunk and on several branches were also damaged. In Fall of 2019 we had a severe temperature change in 30 hours. Temperature went from 80 degrees to well below freezing the next day. The next spring (2020) we had cold and snow after several weeks of mild weather. Between the sun scalding and temperature extremes, the tree didn't live. While it does grow fast and can look nice, I'm not convinced it is a good tree for the Denver area. Our weather seems to be too extreme for this tree. In my opinion.
