Ginkgo trees, also known as the maidenhair fern, are a popular cultivar in North America. It is also known as the ‘living fossil’ as it has been unchanged for millions of years. There are a significant variety of ginkgo trees, so expert advice may be necessary to find exactly the right kind of cultivar.
Most Ginkgo trees are tall, for example: Tubiform Ginkgo (Ginkgo biloba tubifolia). This tree is an interesting variety, where the leaves fuse, and appear like small green trumpets. It grows up to 2 meters in good soil.
Dwarf varieties such as “Mariken”, which grows to 4 feet, have recently been developed, as they are popularly used as bonsai trees.
Ginkgo Pendula (Ginkgo biloba pendula). This is the most frustrating of the ginkgo trees family, as it tends to spread across the ground, rather than growing upwards. In order to achieve height, gardeners have to train it across trellises.
Lacy Ginkgo (ginkgo biloba laciniata). So called due to its lacy leaf edge, which gives it the appearance of a lace collar.
Variegated Ginkgo (Ginkgo biloba variegata). These ginkgo trees have a white or cream stripe along the length of the leaves. These variegated leaves are sparse among generally dark green leaves.
