Ginkgo biloba ‘Little League’ originates from the United States of America. The plant we have in the National Collection of Gingko biloba and Cultivars was supplied as a scion by our good friend Charles Hunter in Iowa and acording to him it originated as a Witches broom. 
 
Description - Ginkgo biloba ‘Little League’.  This cultivar has very unusual foliage, with deep lobes. Somes of the leaves can be found folded in on themsleves. We have only had this plant a short time, therefore it is not possible to give any indication of height and spread, but it is slow growing 10-15 cm a year at present under nursery conditions.
