Emperor 1 (Acer palmatum 'Emperor 1' )

This is one of those ‘Next Big Things’. Emperor 1 is supposed to have good red leaves that stay red in the summer and have a certain translucent quality so that you can see the sun shining through the leaves. It is a nice tree, but I am not sure that I could tell it from a ‘Bloodgood’ if I were really pressed. It does grow reasonably fast to 18′ and then will leisurely get taller, maybe 25′ or so. zone 5
