Showy Milkweed: coarse perennial up to 4 ft; leaves light green or oval; flowers are elaborate and crown-like pink to rose-purple; tan seedpods are three inches long and contain hairs and surrounding the seeds.

• A. Downy Brome
• B. Larkspur
• C. Showy Milkweed
• D. St. John's Wort

Answer: (C)

Understanding plant identification involves matching growth form, leaf shape, flower appearance, and seed structure. The description given—coarse perennial up to four feet tall, light green or oval leaves, elaborate crown-like flowers that are pink to rose-purple, and tan seedpods about three inches long containing hairs around the seeds—fits Showy Milkweed precisely. The pink to purple crown-like flowers and the distinctive three-inch tan pods that enclose silky, hair-like floss used for wind dispersal are hallmark traits of milkweed. Downy Brome is a grass with a loose seed head and does not have crown-like pink flowers. Larkspur produces tall flower spikes with different leaves, not crown-like blooms. St. John’s Wort shows yellow flowers and lacks the milkweed-style seed floss and pod characteristics.
