Persian Ironwood

Persian Ironwood (Parrotia persica)

Persian Ironwood is a refined, four-season tree that brings strong fall color and beautiful bark without needing a huge footprint. It creates comfortable, dappled shade and a polished canopy that fits well in residential landscapes. The foliage stays clean and glossy through summer, then finishes in a mix of yellow, orange, and red tones that can be different year to year. This is a smart choice when you want a tree that feels distinctive up close and still reads well from a distance.

Distinctive Features

Leaves often emerge with reddish to purplish tones in spring, mature to lustrous green, and turn variable shades of yellow, orange, and red in fall. On mature trees, the bark exfoliates to reveal a mottled patchwork of tan, green, and cream, adding winter interest even after leaf drop. In late winter to early spring, small flowers with red stamens appear on bare branches and add subtle early-season detail. The overall form is upright to rounded with a steady, well-branched structure that looks finished with minimal pruning.

Growing Conditions

• Sun: Full sun to partial shade, with best fall color in full sun.
• Soil: Well-drained soil is ideal, and it adapts to a range of soils including clay if drainage is reasonable.
• Water: Medium, keep evenly moist during establishment and water during extended dry periods.
• USDA Zones: 4 to 8.
• Mature Size: About 20 to 40 feet tall and 15 to 30 feet wide.
• Habit: Upright when young, maturing to a rounded to broadly oval canopy.

Ideal Uses

• Focal Point: Plant as a specimen where the exfoliating bark and fall color can carry a main view from the house or patio.
• Shade Tree: Provides light, comfortable shade that keeps planting areas and outdoor spaces feeling open.
• Street Tree: Works well along residential streets where a tough, polished ornamental canopy is needed.
• Courtyard and Lawn Planting: Adds structure and seasonal interest without the scale of very large shade trees.
• Four-Season Backdrop: Pair with evergreens and spring shrubs to highlight bark, foliage, and autumn color.

Low Maintenance Care

• Pruning: Prune in late winter to remove crossing branches and refine structure, keeping cuts modest.
• Watering: Deep water through the first one to two growing seasons to establish a resilient root system.
• Mulching: Mulch over the root zone to conserve moisture and protect roots, keeping mulch off the trunk.
• Soil Management: Maintain good drainage and avoid sites that stay saturated for long periods.
• General: Give it adequate rooting space and avoid reflected-heat sites if irrigation is limited.

Why Choose Persian Ironwood?
