Arnold Tulip Tree

Arnold Tulip Tree (Liriodendron tulipifera 'Arnold')

Arnold Tulip Tree (Liriodendron tulipifera 'Arnold') is a narrow, upright cultivar of the classic American tulip tree, prized for its fast growth, distinctive foliage, and stately form. A selection from the renowned Arnold Arboretum, this cultivar retains the beauty and grandeur of the species while offering a more columnar habit�perfect for urban and compact landscapes that need height without excessive spread. With its golden fall color and signature tulip-shaped flowers, it provides four-season appeal and strong architectural value.

Distinctive Features

'Arnold' sets itself apart with its columnar shape and clean, upright branching. In spring to early summer, the tree produces unusual yellow-green tulip-shaped flowers with orange markings at the base of each petal�though blooms may be less prominent on younger trees. The leaves are bright green and distinctively lobed, turning clear yellow in fall. Its narrower form makes it well-suited for street planting, formal avenues, and locations where space is limited.
