Cultivar is 'Hipazam' ('Hipzam'), as in Highland Park Zampini. (On their introductions page the link to the promotional page fashions the name 'Hipazam SS', on the promotional page it is 'Hipzam'). You can see photos of the leaves and habit at the page linked to below, draw your own conclusions.

If you do a web search for 'Hipazam' multiple nurseries come up, perhaps including other retailers in addition to forestfarm.

Bump! Has anyone grown this tree? Any info would be appreciated

You bet what info are you looking for?

It had mediocre fall color compared to all other maples. Similar to Acer x Celzam vs other sugar maples.

Grew in sandy loam with neutra ph.

Its a dud in my book

How long have you had it? What's the growth rate? Did it have any winter die back? What's the coldest temp it's seen? Was going to ask about fall color specifically, but you answered that one. Sounds like you aren't too impressed with it?

It may perform better in the West.

I no longer have it but it was just under 10 years old. I saw it last year and its fall color was still just ok compared to other maples. I'll check to see if I have pics but don't recall taking any for the lack of fall color.

This one got through the 2012 winter which was considered one of the worst winters in 30 years without any dieback so I'd expect it to perform fairly well in Zone 4 ecspeically if its somewhat sheltered.

Growth rate seemed comparable to other sugar maples but it was a bit more narrow and less vigorous then lets say Fall Fiesta. So its online descriptions appear accurate.

As HM4E mentioned it may have better fall color in more arid climates.

A fiesta of fall color, indeed.

you just don’t see any sugar maples out her, Denver included. I was hoping this tree was a mini sugar maple with tolerance to alkaline soil from the big tooth parentage. I think I will give it a try anyway. It really is a nice tree despite its average fall color. Maybe it will be better here.

nice yard, btw

Fall Fiesta is an amazing cultivar. Both cold hardy and heat/drought tolerant.

I'm pretty sure its the best one out there! Slightly saturated images but its still eye piercing in person.
