They have very specular flowers - in early summer they make large amounts of flower spikes that stands above their foliages, very unusual for a maple to do this. The foliage can be confused with another "moosewood" species of maple which are more of North East US species.

I have no doubt this plant would be happier in a cooler climate, but so far it has performed fairly well and the foliage is quite exciting, especially in the spring.
