These milkweed species are vital for supporting Monarch Butterflies throughout their life cycle, providing food for caterpillars and nectar for adult butterflies. When planting Milkweed, it is important to choose species native to your specific region to ensure their suitability and benefit to local wildlife. This way, we can support the correct ecology for Monarch Butterflies… one day at a time!
