Quercus brantii aka Brant's Oak

Quercus brantii is a deciduous oak in the beech family, Fagaceae. Common names include Brant's oak, Persian oak, and Barro. Its native range runs from eastern Türkiye to western Iran. Records also place it in northern Iraq and Syria. It grows in dry regions with warm temperate climates. Wild plants occur on limestone slopes at varied heights. These sites lie about 1,150–5,580 feet [350–1,700 metres] above sea level.

This fast-growing tree reaches about 26 feet [8 metres] tall. Its mature spread can also reach 26 feet [8 metres]. Kew records its form as either a shrub or tree. It sheds its leaves rather than keeping them year-round. Wind carries pollen between its flowers. PFAF reports that it cannot fertilise itself. It also lists the tree as a plant that attracts wildlife. Its size makes room for a broad crown in cultivation.

Choose an open site with sun rather than shade. This oak accepts sandy, loamy, and clay soils. It needs good drainage but accepts dry or moist ground. It tolerates drought and can withstand coastal exposure. Soil reaction can range from mildly acid to strongly alkaline. PFAF lists USDA hardiness zones 7–9. It reports survival near 23°F [−5°C] during dormancy, perhaps lower. Hot summers may help it withstand winter cold.

The seeds measure about 1.2–2 inches [3–5 centimetres] long. People eat them whole or dry and grind them. The flour can thicken stews or join cereals in bread. Cooking is the usual preparation described for this species. All plant parts contain tannins, so food use needs care. High tannin intake can cause stomach pain and bowel problems. Other reported effects include thirst and increased urination. Traditional medicine uses the seeds, though specific treatments remain unclear.

Fresh seed offers a way to raise new trees. It loses viability when it dries out. Sow ripe seed promptly and protect it from rodents. Cool, moist storage can hold seed through winter. Deep pots suit small batches of seedlings. A deep taproot makes early planting in place important. Older nursery plants can prove hard to move. PFAF lists food-forest use and gives no warning of weed potential.
