The Columnar Oak (Quercus robur 'Fastigiata') is a stunning, upright tree that adds a dramatic vertical element to any outdoor landscape. It is hardy in zones 4-8 and reaches a mature height of 45-50 feet with a width of just 15 feet. This variety of oak thrives in full sun and is a perfect choice for urban landscaping due to its narrow form, making it an ideal option for tight spaces. When planting, we recommend spacing these trees 10-15 feet apart to create a striking, uniform look.Landscape designers can use Columnar Oak to create a formal and structured design, such as by framing entryways or lining driveways. These trees also make a beautiful focal point when clustered together or used in rows to delineate spaces within urban settings. To complement the Columnar Oak, consider planting smaller, lower-maintenance shrubs and perennials that won't compete with its vertical presence, such as boxwoods, ornamental grasses, or daylilies. For a more layered look, consider adding in taller, flowering trees like dogwoods or magnolias for added visual interest.
