showy milkweed
Asclepias speciosaAlso known as Creek Milkweed
Showy milkweed produces spherical clusters of star-shaped, rose-pink flowers that emit a sweet, honey-like fragrance throughout the summer. Its large, velvety, blue-green leaves provide the essential nursery and food source for monarch butterfly caterpillars. This resilient perennial spreads via deep underground rhizomes, helping it thrive in dry, open landscapes across western North America.
