Ginkgo biloba 'Jade Butterflies'Jade Butterflies is a slow growing, dwarf, male tree that grows in an upright, vase shaped form to only 4 6 tall over the first 10 years. However, some authorities estimate this tree may reach as much as 10 12 tall over the first 10 years. Mature height is currently unknown. Deeply bi lobed leaves purportedly resemble butterflies with jade green wings, hence the cultivar name. Foliage turns a uniform and very showy golden yellow in autumn.
