Nice fall color. Someone may know it right away but you'll likely need to get closer with your photos. Photos close enough to see leaves and their arrangement on the stem (3-4' away with a phone) will usually be enough.

....with the caveat that there is not enough detail to positively id, it has the feel of a multi-stem Ohio Buckeye.

I wondered if you'd be able to ID at that distance, but I thought the growth habit might help. It was on someones yard and I didn't want to walk on it. I'm in southern Minnesota.

I drive by there a couple times a week, so I'll dash over and take a closer photo next time.

Ohio buckeye is a good guess. Horse chestnut runs second, generally more likely to be single stemmed than the Ohio buckeye. Both are poisonous in all parts. BTW both are pretty when in flower.

BTW a lot of folks would appreciate your walking up to the front door and complimenting them on the fall color. Those folks obviously take very careful care of their yard. Then you could ask straight out or ask permission to take close photos.

Pretty sure it isn’t Aesculus hippocastanum. The leaflets are the wrong shape.

I'd have to wonder if it is any species of aesculus. The are not known for having very good fall color......typically just a brownish yellow usually described as "unremarkable". Early Glow Aesculus glabra is perhaps unique in this respect in that it has good fall color but quite early.........September usually.

I have little experience with Buckeyes and agree that it is probably not horse chestnut. The image I found show quite a few with similar color and it is hard to completely sort out the leaf shape but that also looks similar. BTW we have not yet had a real frost in central to southern Minnesota; so most trees around here are still holding most of their leaves and a lot have not even turned yet.

I do have a question about the image: Is that another tree behind and above a shorter multistemmed one? If so then you have your brownish leaves in front.

Yes: the first problem with jumping on that species for the identification of the clump in question is that using only the photo provided the compound leaf shape of the buckeye is just not clearly discernible. With the coloring of the leaves at least not being an issue:

Buds sure look like Aesculus

I think it's either a. glabra or a. flava. I don't know how to differentiate between the two. Flava is said to have decent orange fall color..

There is a cultivar called 'Autumn Splendor' that I would describe as having spectacular orange fall color for a few fleeting days. There are a couple in my town. I think this is A. Glabra crossed with something else.. can't remember.

A. glabra has stamens that extend well past the corolla while the stamens of A. flava are mostly hidden within the corolla. You'll be able to tell them apart in the spring.

Generally though, A. glabra is more common in the nursery trade, is more likely to be found in the landscape when outside the ranges of native Aesculus, is generally thought to be hardier then A. flava, and is more suited to be grown as a small multi-stem tree than A. flava.

So, in Minnesota, it's very likely Ohio Buckeye.

Yes: of those two this would be an Ohio buckeye.

Thanks everyone! I found a variety called "Autumn Slendor" and I'm guessing that's what this is. Thanks, again.

That one is a hybrid (with hybrid morphological characters) that was named and dispersed for turning predominantly red. Many pure Ohio buckeye seedlings produce the same generally orange color effect as the tree you asked about here, see for instance at the page I linked to above.
