A striking presence in any landscape, Fagus sylvatica ‘Riversii’—commonly known as the Rivers Purple European Beech—is a deciduous tree celebrated for its bold foliage and elegant form. Native to the woodlands of Central and Southern Europe, this cultivar created by Thomas Rivers made its way to American soil in the late 1800s and has since become a cherished ornamental specimen.

Majestic Form and Structure
Reaching heights of 50 to 60 feet (with the potential to soar to 100 feet under ideal conditions), the Riversii Beech forms a dense, upright canopy with a broad, oval to round crown. Its widespread—up to 50 feet—makes it an exceptional shade tree. The tree’s low-branched trunk (2–3 feet in diameter) and smooth, silvery-grey bark give it a statuesque quality, even in winter.
Foliage Worthy of Royalty
The most captivating feature of the Riversii Beech is its foliage. Its glossy, elliptic leaves (up to 5 inches long) emerge in rich purple tones in spring, transition to a dusky green-purple in summer, and finish the season with coppery hues in fall. This colorful transformation offers multi-season interest that few trees can rival. During the Gilded Age and Progressive Era, such dramatic foliage was especially prized in estate landscapes and public parks, where Riversii Beech became a favored ornamental imported from England to bring a sense of European grandeur to American gardens.
Flowers, Fruit, and Wildlife
Though subtle, the tree blooms in April to May with yellow-green flowers—male flowers in drooping globular clusters and female flowers on short spikes. These give way to small, bristly, triangular beechnuts that are showy and edible for wildlife, though unsafe for dogs.
Growing Conditions and Care
Fagus sylvatica ‘Riversii’ exhibits optimal growth in deep, rich, well-drained soils and demonstrates superior edaphic adaptability compared to its American counterpart, performing reliably in chalk, loam, clay, and sandy substrates. It prefers full sun to part shade and requires only moderate watering. Fagus can be difficult to transplant. It does best when it's dug and planted during the mild mid-spring to mid-summer summer period. For that reason, we will not dig them in the fall. With low maintenance needs and natural resistance to deer, it’s an excellent long-term investment for larger landscapes.
Challenges and Considerations
Like many beeches, Riversii can be susceptible to pests such as aphids, Japanese beetles, and caterpillars. Diseases like beech scale, coral spot, and root or heart rot may appear in older trees, especially in poorly drained sites. Of growing concern is Beech Leaf Disease (BLD), an emerging threat linked to a foliar nematode that affects both native and ornamental beeches, including Fagus sylvatica. While promising treatment protocols are being developed for cultivated landscapes, control remains challenging in forested settings. Still, with proper care, site selection, and proactive monitoring, this regal tree remains a reliable and resilient addition to any property.
