Opinion
"
A. flava is one of the largest North American Aesculus reaching heights of over 30 m. Yellow flowers in May are very attractive although somewhat diminutive (15 cm) when compared to some of its European cousins. It does produce a 'decent' autumn colour display which is somewhat unusual for an Aesculus.
