Carpinus orientalis aka Eastern Hornbeam

Carpinus orientalis is known as oriental hornbeam. It belongs to the birch family, Betulaceae. Its native range spans southeastern Europe and western Asia. This includes southwestern Hungary, Crimea, Turkey, and Iran. It grows as a small tree or large shrub. Dense branches form a bushy crown. Growth is slow, and the leaves fall each year.

Garden trees reach 20–25 feet [6.1–7.6 metres] tall. Shrub forms may reach just 12–15 feet [3.7–4.6 metres]. Rare trees grow to 50 feet [15.2 metres]. The usual spread is 15–20 feet [4.6–6.1 metres]. RHS gives a broader spread of 13–26 feet [4–8 metres]. The leaves grow in an alternate pattern along the stems. Each simple leaf has an oval or elliptical shape. The dark green surface has a gloss and clear veins. Leaf edges have two ranks of small teeth. Fine hairs grow along the central vein. Fall leaves turn yellow or red, without a strong display.

Green flowers form separate male and female catkins in spring. Missouri Botanical Garden lists April as the bloom month. The flowers add little colour to the garden. Female catkins develop clusters of small nutlets. Leaf-like bracts surround the fruit and have coarse teeth. These bracts lack lobes, which helps identify the species. The fruit clusters provide more visual interest than the flowers. North Carolina State lists their display season as fall.

Moist soil with good drainage suits this hornbeam. It grows in clay, loam, sand, and rocky ground. RHS also lists chalk and a wide soil pH range. Light guidance differs between sources. Missouri Botanical Garden favours shade, while Oregon State favours sun. Both report that it tolerates other light levels. Rich soil in part shade is one supported garden choice. Established plants withstand some drought and air pollution. Sources list USDA zones 5–7 and UK hardiness H5. RHS notes that maturity can take more than 50 years.

This hornbeam serves as a woodland tree, hedge, or screen. Its dense form can give privacy in shaded gardens. Its hard wood has supplied tool handles and household goods. People also use the wood for fuel and charcoal. Plants can regrow from root suckers. Seed and softwood cuttings offer ways to raise new plants. Care needs are low, and serious pest problems are uncommon. Aphids and caterpillars may attack it. Leaf spots, cankers, and twig blight can occur. RHS also lists powdery mildew, coral spot, and honey fungus.
