Has anyone compared it to the hybrid Aesculus x carnea cultivars?
They are A. hippocastanum x A. pavia crosses. They can have 5-7 leaflets. The are also used as street trees.
I have no experience with Aesculus x carnea but I have Aesculus pavia. In Aesculus pavia, the new leaves emerge in an upright position right before drooping. They also keep that "droopy and curled around the edges" look for a while. A. pavia has 5 leaflets though, so that's why I wondered about the hybrids which might combine some of the characteristics of both parents.
Here is my Aesculus pavia still sporting its "droopy and curled" look.
