The cutleaf Japanese Emperor oak is certainly a plant for a collector of the plant kingdom's tree oddities. Fine in foliage but excessively slow in growth, this tree will befuddle most who gaze upon it.

The pictures I've contributed to this entry illustrate forty years of effort by one tree to survive in perfectly decent central KY growing conditions. Lack of photosynthetic surface makes a lot of difference in what dimensions a tree might achieve.

Buy it and grow it, but don't expect too much too fast.
