Parrotia Persica

 

(Russian common name, ironwood), a deciduous tree of the family Hamamelidaceae. It attains a height of 14–25 m. Its trunk sometimes puts forth branches as far as the ground, and the branches often take root and fuse with each other as well as with the branches of neighboring trees, such as hornbeam, zelkova, and maple. The bark is gray, in places reddish brown, and peeling. The leaves are leathery and obovate or elliptical. The blossoms are without petals, and two to five blossoms are gathered in heads at the ends of shortened shoots. The calyx has five to seven lobes, and there are five to seven stamens and a half-inferior ovary. The fruit is a woody bivalvular pod, and blossoms appear prior to leafing. The tree may live as long as 200 years.

The species may be found in relict, broad-leaved forests in Azerbaijan (Talysh) as well as in northern Iran (the southern shore of the Caspian Sea), where it grows in lowlands and mountains (up to 700 m above sea level and sometimes higher), on the banks of rivers and streams, and in ravines with moist or, more rarely, dry, rocky soil. The wood is compact and heavy (with a density of 0.9–1.05 g per cu cm), splits easily, lacks resilience, and is very hard and durable (hence the name); it is rose-colored with a brown tint. The wood is used for making certain machine parts, works of art, and decorative veneer.

Ironwood is also the common name of other plants with hard wood, such as the Musaferrea in India, Ixoraferrea in the Antilles, Caesalpinia ferrea in Brazil, Stadmannia sideroxylon on Mauritius, Argania sideroxylon in Morocco, and several species of the genus Sideroxylon.

Look out for parrotia persica, the iron wood from Iran, with foliage that stays on the trees for weeks and gradually turns to the deepest purple, or search out liquidambar styraciflua, the sweet gum from Eastern USA and Mexico with its purple foliage that can remain on the plant for eight to ten weeks.
The yellows, reds, oranges and bronze colouring on plants like acer, parrotia, and fothergilla are so bright and vivid they would stand up against the most vibrant of flowers.
Equally as eye-catching in autumn is Parrotia persica, the Persian Ironwood, which was formerly classified as Hamamaelis or witch hazel.
com The smaller Acers, Cotoneaster, Cytisus battendieri (the pine apple tree), Liquidamber, Salix alba, and Parrotia persica (the ironwood tree) are excellent vehicles for bright red, orange and yellow climbing roses such as Maigold, and the red Parkdirector Riggers.

Parrotia persica - the Iron Wood - a relative of the Witch Hazels (Hamamelis) with a dense, spreading, almost weeping habit, originally from Northern Iran and able to reach 8 metres (25ft) high by 10 metres (30ft) wide.

These forests are more species-rich (including Tertiary relics such as Parrotia, Zelkova, Pterocarya, Celtis, Gleditsia, Diospyros, Liquidarnbar, Liriodendron, and Nyssa genera, as well as more species per genera) than the European alluvial hardwoods for two main reasons: the presence of refuge sites during the Quaternary glaciations, which did not occur in Europe, and the present-day warmer climate (with annual temperatures of 14 [degrees] C and mean annual rainfall of 1000 mm in the Mississippi valley, e.
This develops a more upright habit than most of the species and is slimmer than the common Parrotia.

If I was asked to choose three species from among the larger trees renowned for their tints, at the top of my list would be the Persian ironwood tree, parrotia persica.
Farther on, the reserve's small lake picks up reflections from golden English elms, a yellow-red Persian parrotia, American fothergillas, more Japanese maples, and a European white birch or two.
