Description - Ginkgo biloba ‘Jadwiga’ The leaves are clearly wedge-shaped at the base, and deeply lobed. The foliage is not overly large, and the rate of growth is modest at 20 cm a year. It is too early to suggest the eventual height and spread, however a height of 2m in 10 years can be projected from the growth rate. But the habit has not yet been determined, therefore we cannot speculate about the spread.
