Those tall stalky plants with the thick leaves growing along the fence. The cluster with milky sap your mower flattens every June before it can flower.
That's common milkweed. Native to North America. Here long before the fence was built.
And the only plant monarch butterfly caterpillars can eat 🌿
Monarchs lay their eggs on milkweed because the caterpillars feed on the leaves exclusively — no substitute, no alternative host. When milkweed disappears from fence rows and field edges, the monarchs that depended on it disappear with it.
The plant grows in full sun and well-drained soil — exactly the conditions along fence lines, road edges, and the unmowed strip at the back of the yard. The places it shows up aren't neglected corners. They're the open corridors a migrating butterfly uses to move between breeding grounds and overwintering habitat.
🌱 What to do with milkweed on your property:
- Leave it along fence lines and field edges — mow a clean line around the patch if you want a tidy edge, but let the milkweed itself stand as a defined wildlife island
- Skip herbicide on any strip where milkweed grows. The deep rhizomes hold loose soil on slopes and edges where mowed grass washes out after heavy rain — removing it often creates an erosion problem turf can't solve
- The fragrant pink flower clusters attract a remarkable number of insect species beyond monarchs — native bees, beetles, and butterflies all use them. During WWII, schoolchildren collected the seed pods because the silky floss inside was used as insulation in military life jackets. The plant has been useful longer than most people realize
- If you want more milkweed, don't transplant mature plants — the deep taproot makes them difficult to move. Scatter seed in fall and let winter cold break the dormancy naturally. New stands establish within a season or two
The plant your mower takes out every June is the one connecting a butterfly to a forest a thousand miles south 🌿
