Liriodendron Arnold
Liriodendron Arnold
Upright Tulip Tree
Liriodendron 'Arnold' is a striking, narrow-growing selection of the iconic Tulip Tree, prized for its strong upright habit, distinctive foliage and spectacular golden autumn colour. Unlike the traditional Tulip Tree, 'Arnold' has a much slimmer, columnar form, making it an excellent choice where space is limited but height and impact are desired.
Its unique four-lobed leaves create an architectural look throughout spring and summer before transforming into brilliant shades of golden-yellow in autumn. Mature trees may also produce the characteristic tulip-shaped green and orange flowers in late spring to early summer, adding another layer of seasonal interest.
Ideal for avenues, feature planting, driveways and larger residential gardens, Liriodendron 'Arnold' combines elegance with practicality.
