Why Monarch Butterflies Need Milkweed—But Not JUST Milkweed
About This Resource
Monarch butterflies rely exclusively on milkweed for their caterpillars, which feed on its leaves to grow and metamorphose. The milkweed's toxic compounds protect the caterpillars from predators, making them unappealing to birds. However, the populations of milkweed have declined due to herbicide use, climate change, and habitat loss. To support monarchs, gardeners should not only plant milkweed but also include a variety of nectar-rich flowers that bloom at different times to provide food for adult butterflies. Colorful annuals and native perennials can enhance the garden's ecosystem, attracting not just monarchs but also other beneficial insects. By strategically planting these flowers alongside milkweed, gardeners can create a thriving butterfly garden that supports the entire lifecycle of monarchs and contributes to biodiversity.
Key takeaways
What to know before you act on this, from the SteadScape editors.
- Plant at least three species of milkweed, such as common, swamp, and butterfly milkweed, to support caterpillars in hardiness zones 3-9.
- Include at least five different nectar-rich flowers that bloom from spring to fall, like zinnias and echinacea, to attract adult butterflies.
- Avoid using herbicides in your garden to protect milkweed and other beneficial plants; consider organic alternatives instead.
- Start planting milkweed and nectar flowers in early spring, ideally after the last frost date for your region, to ensure a thriving butterfly habitat.
