At maturity, TSA is 3–6 feet tall and can be as wide as it is tall. Stems, leaves, flower stalks and calyxes have broad-based, white to yellowing thorns up to 0.4 inches long. Pubescent leaves are 4–7 inches long and 2–6 inches wide, deeply divided into broad, pointed lobes. Flowers are white with yellow stamens, a few together on stems below the leaves. Fruits are glabrous, globular, about 1 inch in diameter, and yellow when mature. Seeds are light red-brown, and 0.10 inches in diameter. Seeds are only moderately flattened, contained in a mucilaginous layer that contains a glyco-alkaloid called solasodine.
