Ginkgo biloba (Spring Grove #86)

A brand new dwarf form from a witch's broom found on old trees from the Spring Grove Arboretum in Ohio. It appears to be very small and compact in its form with sturdy closely attached branching. The leaves are typically shaped and emerge in clusters resembling rosettes in the spring.

Brand new dwarf introduction with sturdy trunk and well spaced branching. The contrast of dark green older leaves with a bright green new growth is quite prominent. Mature leaves are deeply divided twice and sometimes three times to the base. In addition they are upwardly often cupped to make a circular outline. The numerous leaf arrangement makes a dense looking
little tree. Estimated to be 15 to 20% the size of the species.
