Ginkgo biloba ‘WB’

Abundantly branched bush with light green leaves. Great for bonsai. Also known as 'Witches Broom'.

A little known form which has proven to be about 1/2 to 1/3 the size of a standard size ginkgo tree, dense symmetrical branching and a sturdy semi- dwarf habit makes this one a real winner.

(JC Ralston Arboretum) - This outstanding new ginkgo is derived from a witch's broom (hence 'WB') mutation that was subsequently cloned. Mature plants exhibit an exceedingly dwarf frame and highly architectural branching structure - creating a bonsai effect in the landscape. Growth rates in landscape settings are slow - 2 to 4 inches per year - but in production, under irrigation and high fertility, are reasonable. Our plant hails from Stanley and Sons Nursery (Boring, OR), a grower of this and several other new dwarf cultivars. A striking new and exciting departure in the world of ginkgo.
