Ginkgo biloba ‘Everton Broom’ is erroneously claimed to have originated in the U.S.A. It was in fact discovered by Stephen Grubb as witches’ broom on Ginkgo biloba at a place called Everton (hence its name), near Lymington, Hampshire in the United Kingdom. It was introduced by Foxhollow Garden in Poole, Dorset to the trade.
