Milkweed plants are mostly native to the United States and Canada with milky sap, fragrant flowers with five united petals, long narrow seed pods, and usually tufted seeds that travel on the wind. Many milkweed butterflies, including Monarch Butterflies, rely solely on milkweed plants to host their larvae. Milkweed gets its name from the acrid milky sap that exudes when the plant is damaged, and probably makes the milkweed butterflies distasteful to predators throughout all their life stages.
