Acer palmatum 'Little Joe'

Acer palmatum 'Little Joe' is a dwarf, green leaf Japanese maple with small green leaves and dense, compact habit.  We've been growing this for a few years under the name 'Tom Krenitski WB' and now see that it has been named 'Little Joe'  For a dwarf, it is extremely fast growing when young and I suspect it might get bigger than the 5' predicted by others.
