Persian Ironwood Parrotia persica
ABOUT
Commonly known as Persian ironwood, this plant is an eye-catching addition to any landscape. It is characterized by a broad, rounded canopy and a habit that creates a picturesque, often multi-stemmed form. The bark of Persian ironwood is one of its most distinctive features, exfoliating to reveal a mosaic of greens, whites, and grays that provide year-round interest. The leaves emerge in the spring with a fresh green hue, some with subtle purple undertones, and as they mature, they develop into a lustrous, dark green. The foliage presents a stunning autumn display when temperatures drop, transitioning through a spectrum of bright yellow, orange, and deep red before falling. Spring also brings small, yet show-stopping, red flowers that lack petals but feature prominent, showy stamens that create a vibrant contrast against the emerging leaves. Following the flowers, the plant produces small brown fruits that may attract wildlife. The overall form and features of the Persian ironwood make it a striking specimen throughout the seasons, offering a dynamic blend of colors and textures to the landscape.

- Water
The Persian Ironwood should be watered when the top inch of soil has dried out, which typically means watering once a week during the growing season and reducing frequency in the winter months. Use enough water to moisten the soil throughout the root zone, which can be approximately 1 to 2 gallons for a medium-sized tree in an average week, but this will vary depending on the size of the plant and the environmental conditions. Over-watering can be detrimental, so it's important to ensure good drainage and never let the tree sit in water.
- Light
Persian Ironwood thrives in full sun to partial shade. The best spot for this plant would be a location where it can receive at least four hours of direct sunlight daily. However, it can also do well in dappled sunlight, which might be preferable in areas with very hot summers.
- Temperature
The ideal temperature range for a Persian Ironwood is between 60°F and 80°F. It can withstand temperatures as low as 30°F and as high as 90°F, but it does best when temperatures are moderate. It is important to protect the tree from extreme cold or sudden temperature drops, which can be damaging.
- Pruning
Pruning Persian Ironwood is mainly done to remove dead or diseased wood and to maintain its natural shape. The best time for pruning is late winter or early spring, before new growth begins. Pruning should be undertaken cautiously and not too frequently as the tree has a naturally attractive form and excessive cutting can lead to poor growth and structure.
- Cleaning
As needed
- Soil
Persian Ironwood prefers well-drained, fertile soil with a slightly acidic to neutral pH, ideally between 6.0-7.0. A mix of loam, peat, and sand in equal parts can create a suitable growing medium for this plant, promoting good root health and moisture retention while allowing excess water to drain away properly.
- Repotting
Persian Ironwood trees are slow-growing and rarely need repotting. They are typically planted directly in the landscape where they can grow undisturbed. If grown in a container, young trees might be repotted every 2-3 years to accommodate root growth, while mature trees can remain in the same pot for longer, provided the soil is replenished.
- Humidity & Misting
Persian Ironwood is tolerant of a wide range of humidity levels but thrives best in moderate to high humidity. It does not require any special humidity requirements when planted outdoors in its appropriate hardiness zones, as it can adapt to the natural environment.
- Suitable locations
Indoor
Provide bright light and space; infrequent watering is key.
Outdoor
Plant in well-drained soil, full sun to part shade; mulch well.
Hardiness zone
4-8 USDA
- Life cycle
Parrotia persica, commonly known as Persian Ironwood, begins its life cycle as a seed, which germinates in the spring to produce a small seedling. The seedling grows through the vegetative stage, developing a strong root system and woody stem, and in approximately 5 to 10 years, it matures into an adult tree capable of flowering. Flowers appear in late winter to early spring before the leaves, with small, red, petal-less blooms that are quite inconspicuous. After pollination, typically by wind or insects, the flowers develop into small, brown, nut-like fruits which, when mature, release seeds to start a new generation. The Persian Ironwood reaches peak maturity over several decades and is known for its remarkable longevity, often living for more than a century. Throughout its life, the plant experiences annual cycles of leaf growth in the spring, followed by a vibrant fall color change and leaf drop in the autumn.
- Propogation
Propogation time
Late winter-early spring
The most popular method of propagation for the Parrotia persica, also known as Persian Ironwood, is via seed. The best time to sow seeds is in autumn, directly after they are collected, as they require a period of cold stratification to break dormancy. This can be naturally achieved by the winter conditions if sown outdoors. Alternatively, stratification can be manually done by mixing the seeds with slightly moist sand and placing them in a plastic bag, which is then stored in a refrigerator at about 34 to 41 degrees Fahrenheit (1 to 5 degrees Celsius) for approximately two to three months. After the cold treatment, seeds can be sown in a well-draining seed starting mix, lightly covered with soil, and kept moist until germination occurs, which may take several weeks. Once seedlings emerge and grow strong enough, they can be transplanted into individual pots or their final location outdoors.
