It's a maple that's probably as close that you're going to get to being nearly sterile.

Reference link below:

"Variation within the species: Red maple forms natural hybrids with silver maple (A. saccharinum): Acer X freemanii E. Murray. The hybrids, however, are nearly sterile."

Thank you, Dax. That is very helpful. I had read somewhere else that the Autumn Blaze maple rarely produced seeds or blossoms, but I wanted to make sure. Having an Autumn Blaze growing in my back yard will not make my allergies any better, but it won't make them worse either. Sometimes the best help is not to hurt.

I think "nearly sterile" in such a context refers to seed production.

I am still researching this tree, but I am hearing that the autumn blaze maple rarely produces seeds or blossoms. No blossoms would mean no pollen, but I am still researching it. I just contacted Poplar Farms, Inc. who developed the Autumn Blaze maple to see if they know for sure.
