Quercus coccinea Münchh.
Scarlet oak
Scarlet oak is a native of the eastern United States, named for bright red colors of its leaves in the fall.
Plants: Trees reach 80′ (24 m), with the maximum reported height of 181′ (55 m). See the Quercus comparison table.
Leaves: Deeply lobed, even more so than eastern black oak, and sharp-tipped.
Flowers: Staminate (male) flowers are borne on slender yellow-green catkins; pistillate (female) flowers are borne on very short axilliary spikes. Both are brown, and inconspicuous.
Fruits: Acorns are ovate, ⅝–1¼″ long ⨉ ¼–½″ around (1.7–3.1 cm ⨉ 7–13 mm). The cap usually covers a third to half of the nut.
Habitats: Dry to somewhat dry well-drained, acidic soil, in full sun.
