Aesculus pavia (Red Buckeye)


Michael's Opinion

Similar in initial character to A. x carnea but not as worthy a placement in the landscape. Flowers are interesting but after having experienced A. x carnea this is a poor substitute. The size may be its redeeming quality since where one wishes the attributes of A. x carnea but does not have the room, this is the second choice.
