Monarch butterflies, with their strikingly streaked caterpillars, gold-foiled chrysalises, and tiger-striped wing patterns, are one of the most beloved of all butterflies. We humans flock to witness monarch migrations, but we are also responsible for their decline. Loss of habitat and exposure to pesticides threaten monarch populations from Canada to Mexico. Grow Milkweed, the monarch caterpillar's host plant, to create a monarch sanctuary in your own backyard. Create a companion planting of Butterfly Weed for very happy butterflies.

Use: Cold stratification required: direct sow in fall or early winter into a clean, prepared bed. Or, for spring sowing, sow in deep seed-starting pots about ¼" deep, in rich, damp soil. Cover and refrigerate for 3 weeks. Afterwards, move to a 70-degree, well-lit spot for germination, which can take up to 14 days. Transplant outdoors after frost in an area that can remain a milkweed patch for years.
Please note: Common milkweed (Asclepias syriaca) is native to much of the eastern and mid continental U.S.—most areas east of the Rocky Mountains. If you live outside of these areas, please do not buy or plantAsclepias syriaca. Before planting any milkweed, it's always a wise idea to referencemonarchwatch.orgor theXerces Societyfor more information on milkweed species that are native to your specific area.
