The green leaves of allium bisceptrum are flat rather than cylindrical, and persist during the flowering stage. Plants have between two and five leaves, pointing upwards, generally slightly less tall than the stem - up to one foot. Leaves are pointed at the tip and sheathed at the base. Plants typically produce one, two or three stems.

The inflorescence contains between 15 and 40 flowers, on hairless green stalks of up to one inch. Flowers have six lanceolate tepals, blunt-pointed at the tips, colored white (usually), pink or purple, greenish at the base. The flower cluster is subtended by a pair of pointed, equally-sized bracts, crossed by several prominent, lengthwise, reddish veins.
