Could be A. parviflora,
Its a shrub. a buckeye… colloquially known as bottlebrush buckeye. telltale is the narrow inflorescence (unlike the horse chestnut tree we all love).
Beautiful upload. Yes it is A. parviflora (Bottlebrush buckeye). The ID is correct. I have also seen this in Princeton (New Jersey) around & photographed.
For me the ID looks correct. Cultivated. I have seen this in California area.
