Popular common name:
Green antelopehorns
Botanical Nomenclature:
Asclepias viridis
Asclepias viridis, commonly known as green antelopehorns, offers a unique advantage for gardeners looking to support migrating monarch butterflies. Its growth cycle perfectly aligns with the timing of monarchs arriving from Mexico, providing a critical food source during their migration. The plant's distinctive green, horn-shaped seed pods and clusters of fragrant greenish-yellow flowers not only add visual interest to the garden but also attract a variety of pollinators. By planting green antelopehorns, you create a welcoming habitat that supports the life cycle of monarchs, as they lay their eggs on the foliage, ensuring a healthy population for future generations. Additionally, its adaptability to a range of soil types and conditions makes it relatively easy to grow, requiring minimal maintenance while enhancing biodiversity in your landscape.
