A tree occurring naturally in North America on moist but well-drained soils. In warm climates semi-deciduous to evergreen, in cold climates mostly deciduous. In the wild it attains a height of 30 m but when cultivated only reaches 15 to 20 m. The smooth dark grey bark becomes rough in older specimens and flakes off in small platelets. Young olive-green shoots are covered with downy hair but quickly become bare and brownish-green. The leaves are narrow lanceolate to sometimes linear and closely resemble those of the willow. They are 5 - 15 cm long and 1 - 1.5 cm wide. On the upper side dark green, the underside bluish-green. The smooth leaf edge is slightly undulating. The autumn colour is light yellow in regions where the leaves fall in the winter. The acorns are at the most one-third enclosed in the cupule.

Správny čas na výsadbu stromu je mimo vegetačné obdobie. V strednej Európe môže byť Quercus phellos so zemným balom vysadený od polovice novembra do konca apríla, avšak závisí to veľmi od klimatických podmienok a druhu stromu.
