Spider antetope-horns is a clump-forming, 1-2 ft. perennial with an upright or sprawling habit. Stems are densely covered with minute hairs. The leaves are 4–8 inches long, narrow, and irregularly grouped. The long, thick, narrow leaves are often folded lengthwise. As the green seed pods grow in length and begin to curve, they resemble antelope horns. Its pale, greenish-yellow flowers, tinged maroon, are crowded in round, terminal clusters 3–4 inches across at the end of the flower stem and are intricately arranged. Inside the partially divided petals is a crown, out of which extend 5 white stamens with large, ball-like anthers, all symmetrically arranged.
Milkweeds are the primary food source for Monarch caterpillars.
