Ginkgo biloba 'Jade Butterflies' Very dwarf and dense Ginkgo with bright yellow fall color. The form, branch structure, and bark adds nice winter interest. Gets lots of attention from garden visitors. Pest and disease resistant. Easy to grow. Very slow growing, less than 1' of growth in the 5 years we have owned this tree. Ours was grown by Bizon nursery. Name comes from the leaf shape of a butterfly, when viewed from above as seen in photo two.
