The Story

Plant Bio

Ginkgo biloba, the Maidenhair Tree, is a unique deciduous tree with no close living relatives, often called a 'living fossil.' It is prized for its distinctive fan-shaped leaves and brilliant golden-yellow fall color. 'Sky Tower' is a male selection with a very narrow, fastigiate form, making it an ideal choice for tight urban spaces, as a formal street tree, or as a strong vertical element in landscape design.

Uses & Benefits:

A tree of immense beauty and history. It provides unique, fan-shaped summer foliage that turns a uniform, brilliant, buttery yellow in autumn. The narrow form of 'Sky Tower' is highly architectural and elegant.

Its extreme tolerance of pollution, salt, heat, and confined soil spaces makes it one of the best trees for difficult urban environments. The narrow habit is perfect for lining streets or driveways without obstructing views or traffic.

As a 'living fossil,' planting a ginkgo is an act of conservation for a unique botanical lineage. While it doesn't support a wide range of native insects, its durability makes it a reliable green presence in harsh urban settings.

Planting

How to Grow

Select a location in full sun for best growth and fall color.
This tree is highly adaptable to most soil types, including clay and sand.
Dig a hole two to three times as wide as the root ball.
Set the tree in the hole so the root flare is at or just above soil level.
Backfill with the original soil and water thoroughly.
Water regularly for the first year to help it establish.

Pro Tip

Be patient. Ginkgo trees are slow to establish and may exhibit very little growth for the first couple of years after planting.

Keep It Thriving

Care Guide

Do

Provide full sun for the most vibrant yellow fall color.
Water deeply when young to encourage a strong root system.
Allow it plenty of time to establish; it is notoriously slow to start.
Appreciate its pest-free and disease-free nature.

Don't

Do not plant a female or unsexed seedling tree in a residential area.
Avoid planting in poorly drained or constantly wet soils.
Don't be alarmed by its slow initial growth rate.
Avoid heavy pruning, which is unnecessary and can spoil its form.
