For California, the best milkweed species to support monarch butterflies and other pollinators is Asclepias fascicularis, a native plant commonly known as Narrowleaf milkweed or Mexican whorled milkweed.

Since it is native to California, it is well-suited to the local climate and soil conditions. Milkweed serves as a vital host plant for monarch butterflies, providing a place for females to lay their eggs and food for the caterpillars.

When establishing a pollinator garden with Narrowleaf milkweed, it is essential to include other native flowering plants that bloom at different times to provide a continuous source of nectar and habitat for pollinators throughout the year. Always ensure that the milkweed you choose is native to your specific region in California, as different regions may have other native milkweed species that are better suited to local conditions.

If plants are not available at your local garden center, they can be preordered for Fall from High Country Gardens.
