Yucca queretaroensis has a tall trunk up to 12 feet (4 m) high, with a large, prominent skirt of dead leaves hanging around the stem underneath the crown of living leaves. Leaves are very narrow, no more than 3 mm (1/8 inch) across, square in cross-section. Flowering stalks rise up to 1 m above the crown, bearing white flowers.[4][5][6][7]
