Parrotia persica is a small tree that works well in urban landscapes and usually does not fall prey to diseases or pests. The bark can also come in many shades of brown, gray, green and white. It peels off attractively.
Like many species in the Hamamelidaceae family, Persian parrotia puts on a splendid fall color show. After the red-hued leaves unfurl in spring, they change to green as the year advances.
In autumn they change again to become shades of orange, yellow and red.
This plant is a member of the Hamamelidaceae (witch hazel) family and has been designated as Parrotia persica. It is the only species in that genus. Other members of Hamamelidaceae that you can find in gardens include witch hazel (Hamamelis virginiana), dwarf fothergilla (Fothergilla gardenii) and American sweetgum (Liquidambar styraciflua).
It is referred to as Persian parrotia, Persian ironwood, and parrotia.
Preferred USDA Hardiness Zones:
For best results, this should be grown in USDA Zones 5-8. It is native to northern Iran, formerly known as Persia.
Size & Shape:
This tree reaches a mature height of 20-40' tall and a width of 15-35'. It will reach a round or vase shape.
This tree will grow well when located in a site with full sun or part shade. Trees in part shade will most likely have autumn colors that are more muted than those in full sun.
The leaves are oval with wavy margins. They first appear in a red shade in spring. Summer has them shifting to green. Before they fall off in autumn, the leaves change to red, yellow and orange.
The flowers on this tree are incomplete and appear before the leaves. They do not form petals and the rich red parts that you start seeing in late winter are clusters of stamens.
Each flower forms into a capsule that is split in two. Each side holds one seed.
Design Tips For Persian Ironwood
Since this tree is on the smaller side, it works well as a street tree where power lines are a consideration.
Parrotia persica is perfect as the specimen tree in a small garden.
If there are oak trees nearby, you may not want to plant this species. It is a known host for Phytophthora ramorum, the pathogen that causes sudden oak death.

Growing Tips For Persian Ironwood

Maintenance and Pruning
You will need to decide whether you would like this tree to have several trunks or just one.
If you choose to have just one, you need to prune it to create a central leader when it is young. Most other pruning is for aesthetic reasons, such as branches forming in a direction where they are not desired.
Pests & Diseases
Another attractive feature of this tree is that you will have few if any problems with pests and diseases.
