Fagus sylvatica 'Tricolor' (Tricolor Beech)


Michael's Opinion

One of the most admirable cultivars of this species. It is often confused with Fagus sylvatica 'Roseo-Marginata' and Fagus sylvatica 'Purpurea Tricolor', which have purple and pink variegated foliage while the cultivar 'Tricolor' has green, pink and cream variegated foliage. A radiant medium sized shade tree, no matter the season. Low maintenance and well formed, some specimens have lived to be 120 years old. Easily recognized by its leaves and low growing canopy with some of the lower branches not even clearing a metre off the ground. A truly stunning tree no matter the time of year.

Description and Growing Information

General DescriptionMedium size deciduous tree with low canopy. Insignificant buds and flowers, but eye-catching green, pink and cream variegated foliage in the spring and summer. Admirable copper coloured leaves in the autumn and stunning grey bark in the winter.
ID CharacteristicEasily recognized by its colourful obovate and alternating, green, pink and cream variegated foliage and its low, full canopy.
ShapeOval and upright-pyramidal in form.
LandscapeIdeal for a focal point, landscape or specimen tree and offers great colour no matter the season, even in the winter the bark is a beautiful colour. Grown strictly for its foliage and to a lesser degree the smooth grey bark, as its flower and fruit are both small and insignificant. The tree performs best in partial sun as this prevents its pale variegated foliage from scorching and turning brown.
PropagationScions of 'Tricolor' should be grafted onto F. sylvatica rootstock.
CultivationThe tree should be planted in partial shade as full sun often burns or scorches the foliage. It requires adequate moisture, but will not endure standing water and prefers rich well drained soils but is not partial to a specific pH; it will sustain mild urban pollution.
PestsCanker, powdery mildew, leaf spot, borers and aphids may be of concern however in my experience aphids are the most common pest but are such a minor concern that they do not warrant control.
Notable SpecimensThe A. M. (Mac) Cuddy Gardens, Strathroy, Ontario, Canada.
