Beautiful tree; bright read seed in the spring, much brighter than red maple; nice leaf in spring and summer; no significant disease or pest, but I had some borer; Amazing fall colors, almost luminescent yellow/orange/red.
The trunk is a little thin when young, thinning canopy helps decrease the wind resistance the prevent splitting of breaking; the bark is thin and deer can damage it easily.

Autumn Blaze does very well in Edmonton zone 3b. It is definately not only hardy to zone 5a. This tree has amazing fall color but depending on the year, can turn color very early (is very sensitive to temperature drops). The color does last a long time. There are a couple on my street that have held their color for longer than a month! Does not mind the neutral-slightly basic Edmonton soil.

I was told this maple was more tolerant of Utah's alkaline soils than other red maples, but I see the description above say it likes acid-to-neutral soil. I have one doing very well, one pretty good, and one clearly chlorotic. I need to figure out if there's something I can do about the chlorosis. They've all grown well, and I don't have any problems with them breaking as the previous writer said. Mine were never staked and have survived wind storms and are quite thick after four years.

While this hybrid is meant to be stronger than silver maple, I lost two out of 4 trees (about 2" caliper) which 'snapped' about 4 feet off the ground during a gusty day (not a storm by any means). Their growth rate is phenominal, but they became so top heavy they were unable to support their canopy.
