Persian Ironweed Tree - Parrotia

Persian Ironwood (Parrotia persica) is a stunning, low-maintenance ornamental tree perfectly suited to Southwestern Ontario's Zone 5–6 climate. Prized for its dramatic seasonal transformations, this hardy tree delivers year-round visual interest with burgundy spring foliage, deep green summer leaves, and brilliant orange-red fall color. Winter reveals exfoliating bark in shades of green, white, and tan—a striking feature when deciduous trees are bare. This tree thrives in full sun and adapts to most soil types, though it prefers well-drained, slightly acidic conditions. Once established, it is remarkably drought-tolerant and requires minimal pruning. Tiny red flowers appear in late winter before the leaves emerge, adding early-season charm. Naturally pest and disease-resistant, Persian Ironwood grows at a slow-to-moderate pace, reaching 20–40 feet at maturity. It is highly salt-sensitive, so avoid planting near roads treated with de-icing salt. Newly planted trees benefit from wind protection during their first winter. With regular watering in year one and consistent moisture during dry Ontario summers, this exceptional tree will reward you with decades of beauty and resilience.
