(Known in China as ‘Tazhuang Ginkgo’) Ginkgo biloba 'Mariken' is a male form. Following a tip provided by Mr. P. Theunissen of Beesel, in The Netherlands, Piet Vergeld saw a Witch’s broom in 1995 growing on a tree in Kronenburger Park in the City of Nijmegen, in The Netherlands. It was a large and loose mutation. He harvested some material and grafted it. The plant was named ‘Mariken’ after Mariken van Nieumegen, a famous female from medieval literature. David Bomer, of Boomkwekerij David Bömer, Vagevuurstraat 6A, 4882 NK Zundert, Netherlands claims that it was introduced into the trade by his nursery. Regardless of whom introduced the plant, it is a good cultivar with stable characteristics that has become a firm favourite.
