Possibly. That is.  We have two very slow growing horse chestnut of Chinese/Japanese ancestry. Never precisely identified! Very elegant cream/gold flowers, spectacular pink buds in the spring, about 15 feet by 15 feet at close to forty plus years old. A few years ago I managed to get a nut from one to actually sprout, hopefully it will grow.  At the moment it is still at the stage of having just one massive terminal bud each year, which makes one nervous.

Here is the flower bud from one of the original ones a few days ago, that flower will eventually be 6 inches tall:
