Quercus falcata (Southern red oak)
Wasowski, Sally and Andy

Quercus falcata

Quercus falcata Michx.

Southern red oak, Spanish oak

Fagaceae (Beech Family)

Synonym(s): Quercus falcata var. triloba, Quercus triloba

USDA Symbol: QUFA

USDA Native Status: L48 (N)

Southern red oak is a medium-sized, straight-trunked oak which, in time, develops long, spreading branches, giving the top an even, well-formed appearance. Its smooth gray bark becomes dark and furrowed, eventually becoming black. Thin, papery, lobed, bristle-tipped deciduous leaves turn reddish-brown in fall. Twigs pubescent reddish-brown twig with star shaped pith; reddish-brown terminal bud is ovoid and pubescent. Leaf petiole 3/4 - 2 3/8 inches (19 - 60 mm) in length, smooth to sparsely pubescent; leaves are elliptical to ovate, 4 - 11 3/4 inches (101 - 298 mm) long and 2 3/8 - 6 1/4 inches (60 - 159 mm) wide, u-shaped base, margin has 3 - 7 deeply divided lobes with 1 - 3 bristle-tipped teeth, apex longer than lateral lobes; upper surface a glossy green often with some pubescence along midrib, lower surface covered with gray or tawny pubescence, secondary veins raised on both surfaces.

Often called Spanish Oak, possibly because it commonly occurs in areas of the early Spanish colonies. It is unlike any oaks native to Spain. The lumber is marketed as Red Oak. Cherrybark Oak (Q. pagoda Raf.) is sometimes considered a variety of Q. falcata (Q. falcata var. pagodifolia Ell). The lobes of its leaves taper to points that remind some people of the graduated roofs of pagodas. The leaves have 5-11 broad shallow lobes and whitish hairs beneath, and the bark is smooth and cherry-like with short ridges.

Propagation

Description: Oaks are most often propagated from seed. Stratify seeds. Plant outdoors or in deep containers to accomodate long initial taproot. Many oaks require cold temperatures to initiate shoot development. Protect outdoor beds with wire mesh to deter rodent p
Seed Collection: Best quality acorns are picked or shaken from the tree. Collect when color has changed to brown. Best if sown immediately as acorns lose viability quickly in storage. Short-term storage in moist, shaded saw dust or sand. Acorns to be sown immediately can be soaked in hot water for 15 min. to prevent weevil infestation. Stored seed should be fumigated with methyl bromide.
Seed Treatment: Stratify seeds in moist sand or potting soil for 30-60 days at 32-38 degrees.
Commercially Avail: yes
