Red Obelisk Columnar Purple Beech

Fagus sylvatica 'Red Obelisk' is a narrow, columnar beech with red-purple leaves that develop bronze-purple tones in autumn. It combines a strong vertical outline with seasonal foliage color and is also listed under the synonym 'Rohan Obelisk'. ## Garden Use Use it as a vertical accent where a broad shade tree would crowd paths or nearby planting. The Royal Horticultural Society describes a mature height of 8 to 12 metres and a spread of 1.5 to 2.5 metres; Oregon State University notes the purple, variably lobed foliage and the cultivar's columnar habit. The mature canopy still needs room, so keep it clear of buildings and overhead obstructions. ## Growing Conditions Full sun brings the strongest leaf color, while partial shade is also tolerated. The RHS lists chalk, clay, loam, and sandy soils and recommends moist but well-drained or well-drained conditions. Beech roots and canopy need adequate soil volume, even for an upright selection. ## Maintenance Allow the crown to develop naturally and remove only damaged or crossing branches when needed.
