Ginkgo Trees

Ginkgo Trees, Ginkgo biloba, also known as Maidenhair Trees, are a staple in any Asian or zen garden and landscape. Although very slow growing, they mature into large shade trees. You may be familiar with Ginkgo trees because of their fan-shape leaves that turn a vibrant yellow in fall as the tree swiftly defoliates or from the common misconception about their smell. We're discussing the overall family characteristics, including some of the similarities and difference between the cultivars available, like Magyar Ginkgo, Autumn Gold™ Ginkgo, and Princeton Sentry® Ginkgo.

Family History

The genus name of Ginkgo is a missed translation of the Japanese ‘gin’ meaning silver and ‘kyo’ meaning apricot dating back to the 17th century. A long-time symbol of longevity, the Ginkgo’s history is an astonishing one.

Ginkgo trees are known as a living fossil, with leaf impressions dating back 270 million years!! It is also a readily available medicine throughout the world. It is often claimed that many species are resilient, but how many can say their species has survived the Atomic bomb dropped in Hiroshima? Roughly 170 Ginkgo biloba survived the blast in 1945. Read the story here. Talk about a living legend! A true symbol of longevity, this tree will most likely outlive generations to come. These trees can live for over 1,000 years, and when given the proper planting care you should expect yours to do the same.

Ginkgo Wildlife Value

Ginkgo trees are not Wisconsin native or regional native to the Midwest. Cultivars typically available in the marketplace are seedless (male) plants; therefore, they do not produce seed. Aside from the benefits of leaf food or branching for nesting materials, they provide little value to wildlife or nature's food web.

Suggested Uses For Ginkgo

Ginkgo trees have a wide range of usage. Since they're very hardy: tolerant of a wide range of soils, salt tolerant, and deer resistant, they may be used for commercial and residential landscapes, specimen gardens, as street trees, or in urban settings. Factors for consideration in planting and siting Maidenhair trees are light availability and space for their mature size. You'll see below that one of the cultivars is more columnar; therefore, it's suitable for sites with less space, but the other two may mature to 20-30 foot spreads. As with all Ginkgo trees, they require full sun, but can tolerate partial shade.

Do They Smell?

We mentioned the male/female relationship with seeds briefly above: "Cultivars typically available are seedless (male) plants." Females produce a fruit which is known to bring an unpleasant smell with it, making it industry standard to sell male cultivars.

Dramatic Fall Defoliation

In fall, you may notice your Ginkgo’s leaves drop dramatically, all at once. Why is this? As colder weather comes, common deciduous trees like maples often lose their leaves over the course of a few weeks.

The process of a tree losing its leaves it a little more complex than you may think, the stems of leaves on these trees are called petioles. Petioles produce a layer of protective cells to protect trees from diseases that could enter as the leaves drop. This process typically takes place over a period of several weeks as temperature decreases. On a Ginkgo tree, the petioles form this layer of scar-like cells simultaneously and once a hard frost comes it triggers all leaves to drop at once, creating a lovely golden carpet around the base of your tree.

Often, a true sign that fall has arrived.

Cultivars

As they are pretty much the same tree across the board, the differences are their mature spreads (widths). If you're unfamiliar with cultivars, watch our video Cultivar - What is it?
