The solitary Yucca confinis forms a short trunk. The irregularly arranged, smooth, stiff blue to green leaves are 0.5 to 0.8 meters long and form fibers on the leaf edges.
The upright or branched, branched inflorescence that begins between the leaves is 1 to 1.3 meters high and protrudes above the leaves. The pendulous, spherical, hermaphrodite flowers are about 6 to 12 cm long and 2 to 3 cm in diameter. The elongated, white, cream-colored bracts are 5.5 to 9 cm long. The flowering period extends from March to April. The cylindrical fruits up to 20 cm long are characteristic.
