Ginkgo biloba ‘Sky Tower’ is a very narrow, columnar form of ginkgo valued for tight spaces and vertical accents in the landscape. It typically grows slowly to moderately, reaching about 10–12 ft tall in 10 years with a spread of roughly 3–5 ft under average conditions. Like other ginkgos, it is extremely hardy, drought tolerant once established, and resistant to pests and disease, with clean golden fall color. It is a male selection, so it produces no messy fruit, making it especially low-maintenance for residential or urban plantings.
