Oak, Concordia

Concordia Oak (Quercus robur 'Concordia')

Concordia Oak is a striking golden-leaved selection of English Oak that brings brilliant color, stately form, and lasting beauty to the landscape. One of the oldest cultivated oak selections, introduced in the 1800s, 'Concordia' is prized for its glowing golden-yellow spring foliage that gradually softens to yellow-green through summer. Slower growing and smaller than the species, it is an excellent specimen tree for gardens where dramatic foliage and long-term landscape value are desired.

Key Characteristics

Golden foliage that shines throughout the growing season
New leaves emerge an eye-catching butter-yellow, creating one of the brightest displays of any hardy shade tree. As the season progresses, the foliage matures to a soft yellow-green, maintaining a luminous appearance that contrasts beautifully with darker trees and shrubs. In cooler autumn weather, the foliage transitions to warm golden tones before leaf drop.

Acorns and Garden Character
Acorns provide food for birds and small mammals. Concordia is an ornamental selection of English oak, whose native range is in Europe and western Asia; it should be identified as a cultivated non-native oak in a native-plant plan.

An elegant specimen for long-lived landscapes
Unlike the massive English Oak, 'Concordia' grows more slowly and develops a compact, rounded canopy, making it easier to incorporate into residential landscapes. Its brilliant foliage makes it a natural focal point in parks, estate gardens, and mixed tree plantings where seasonal color is a primary design element.

Built for generations of beauty
Once established, Concordia Oak is exceptionally durable and long-lived, adapting to a wide range of soil types and urban conditions. It tolerates drought better with age and develops the strength and permanence that make oaks among the finest legacy trees. In hotter climates, some afternoon shade helps preserve the vivid golden foliage and minimizes leaf scorch.
