Columnar Persian Ironwood

Columnar Persian Ironwood (Parrotia persica 'JL Columnar')

Columnar Persian Ironwood (Parrotia persica 'JL Columnar') is a vertical-growing selection of Persian Ironwood prized for its striking foliage, upright form, and year-round landscape interest. This cultivar adds architectural structure to gardens with its narrow silhouette, rich fall color, and exfoliating bark.

Distinctive Features

'JL Columnar' maintains a dense, upright, columnar shape, typically reaching 30 feet tall but only 10 to 12 feet wide, making it ideal for narrow spaces or as a vertical accent. New foliage emerges reddish-purple in spring, maturing to deep green by summer. In fall, the leaves shift to a brilliant mix of yellow, orange, and red. Even in winter, the plant holds ornamental value through its smooth, mottled bark in tones of gray, green, and white.
