Ginkgo biloba 'Obelisk'

A medium to large, slow-growing deciduous tree to around 4m in height, with an upright, columnar habit. Fan-shaped leaves emerge pale green in spring, turning darker green in the summer then golden in the autumn. Green flowers appear in April, but as this is a male cultivar, it will not produce fruit. Makes an attractive addition to smaller gardens and patios where space is at a premium
