TWELVE NATIVE MILKWEEDS

Did you know that there are over two hundred species of milkweed (Asclepias) found around the world? Seventy different species are native to North America.

Milkweeds, as most know, are the host plant for Monarch Butterflies. A host plant is another way of saying caterpillar food plant. Monarchs deposit eggs on milkweed plants. Some milkweeds are more productive than other species. For the Northeast region, the most productive milkweed is Common Milkweed (Asclepias syriaca). The second most productive is *Marsh Milkweed (Asclepias incarnata). What is meant by productive? When given a choice, the females choose these plants over other species of milkweed and the caterpillars have the greatest success rate. In our own butterfly garden and at at my client’s habitat gardens, I grow both side-by-side. The females flit from one plant to the next, freely depositing eggs on both species.

This fun chart shows some of the most common species of milkweeds found in North American gardens. *Swamp Milkweed is another common name for Marsh Milkweed.
