Quercus falcata, also called southern red oak, spanish oak, bottomland red oak or three-lobed red oak is an oak (part of the genus Quercus). Native to the southeastern United States, it gets its name the "Spanish Oak" as these are the areas of early Spanish colonies, whilst "southern red oak" comes from both its range and leaf color during late summer and fall. The southern red oak is a deciduous angiosperm, so has leaves that die after each growing period and come back in the next period of growth.
Quercus falcata is a medium to large-sized deciduous tree 25â30 meters (82â98 ft) tall, with a few forest grown specimens on highly productive sites reaching 35â44 meters (115â144 ft), with a trunk up to 1.5 meters (5 feet) in diameter, the crown with a broad, round-topped head.
The leaves are 10â30 cm (4â12 in) long and 6â16 cm (2 1â4â6 1â4 in) wide, with 3 to 5 sharply pointed, often curved, bristle-tipped lobes, the central lobe long and narrow; the small number of long, narrow lobes is diagnostic, readily distinguishing southern red oak from other red oaks. The base of the leaf is distinctly rounded into an inverted bell shape and often lopsided. They are dark green and shiny above, and rusty and hairy below, particularly along the midrib and veins.
The seed is a short acorn 9â16 mm (11â32â5â8 in) long, bright orange-brown, enclosed for one-third to half of its length in a flat cup. The acorn matures at the end of its second season. The bark is dark brownish gray with narrow, shallow ridges.[4]
Southern red oak has been reported to form occasional hybrids with several other red oaks in the region. the southern red oak is cultivated in eastern United States in USDA Zone 5a to USDA Zone 9b can survive lows from -23°c to -28.8 °C (-10°f to -20 °F) and highs of 38° C (100° F)
