8.Ginkgo biloba

Common name: Ginkgo

Family name: Ginkgoaceae

Useful cultivars and selections:

Ginkgo biloba ‘Fastigiata’:Fastigiate or columnar ginkgo forms have been available in commerce for over 100 years. Nurseries often sell these forms under several different labels including Ginkgo biloba forma fastigiata, G. b. fastigiata or G. b. ‘Fastigiata’. These fastigiate forms (fastigiate meaning upward branching) typically grow 30-50′ tall with upright, narrowly conical habits that are just slightly broader at the base. ‘Fastigiata’ is an all-male cultivar. Leaves turn a uniform golden yellow in autumn (spectacular when backlit by early morning or late afternoon sun) and persist for several weeks. When the leaves do drop, they drop rapidly, forming a golden carpet around the tree.

Ginkgo biloba ‘Magyar’An introduction that is gaining momentum in the trade, this plant is a non-fruiting male with upright, ascending branching to 60′ tall and half as wide. It is well-suited to urban planting as a street tree.

Ginkgo biloba ‘Chi-Chi’ Dwarf, dense, mounded, slow-growing, multi-stemmed shrub form of the popular ginkgo tree. It typically grows to only 4-5′ tall with a fan-shaped habit and over 10 years. ‘Chi-Chi’ is a male clone. Its cultivar name translates as “breasts” in reference to unusual swellings (clusters of dormant buds) which appear on the bark of plants as they mature (usually after 10 years). Leaves turn a uniform golden yellow in autumn.

Ginkgo biloba ‘Tubifolia’ ‘Tubifolia’ (synonymous with ‘Tubiformis’ and ‘Tubeleaf’) is a tubular-leaved, slow-growing male form that typically grows to only 3-4’ tall over the first five years. It is particularly noted for having variable leaf shapes. On younger trees, leaves typically roll inward forming tube. As trees grow older, the leaves tend to flatten out, but with a more laciniate form than species leaves. This tree may eventually mature to as much as 20-25’ tall. Light green leaves turn an excellent golden yellow in fall.

Ginkgo biloba ‘Jade Butterflies’: An unusual dwarf, slow-growing form, this plant has bright green leaves and a mature height that is less than half that of standard forms. It’s an introduction out of New Zealand that is gaining popularity.

Ginkgo biloba ‘Shangri-La’ :’Shangri-La’ is a more compact well-branched tree with a full and balanced crown. It typically matures to 55′ tall and to 40′ wide. It is a male tree that was discovered in 1963 in a planting of seedlings in Urbana, Illinois by Willet N. Wandell. U. S. Plant Patent PP 5,221 was issued on April 17, 1984. Patent documents describe the unique features of this male tree as: (a) rapid compact growth habit, (b) dense full crown with balanced moderate spread, and (c) freedom from production of the foul smelling fruit produced by female plants. As with species plants, the fan-shaped leaves are rich green to blue green during the growing season, but change to an often spectacular bright yellow in fall. Dangling staminate catkins (April-May) are not ornamentally significant.

Ginkgo biloba ‘Troll’ :‘Troll’ is a dwarf shrubby cultivar that matures over time to only 3′ tall and as wide. It typically grows in a bushy mound, although it can be trained to grow as a small pyramidal tree. As with species plants, the fan-shaped leaves (biloba means two-lobed) are rich green to blue green during the growing season, but change to bright yellow in fall.

Ginkgo biloba ‘Mariken’Can‘t find description

Ginkgo biloba ‘Autumn Gold’: This male (non-fruiting) selection is common in the trade and notable for its symmetrical crown that is broad and rounded. The mature size is 50′ tall with a 30′ spread and fall color is an excellent deep yellow.

Ginkgo biloba ‘Pendula’:Plants listed under this name are quite variable, with few expressing a strong weeping habit. Most bear branches that are horizontal or droop slightly

Ginkgo biloba ‘PNI 2720’:A very popular non-fruiting male form, this form assumes an upright habit that tapers to the point. It reaches 60′ tall, but only 25’ wide.

Ginkgo biloba ‘ Saratoga’:Commonly offered, this plant has a strong central leader and an upright, narrow habit (40′ tall and 30’ tall).

Ginkgo biloba ‘ Variegata’Many different clones are offered under this name, but most feature leaves that are irregularly streaked with yellow.
