Common Milkweed is a gorgeous native flower that is the sole source of food for the Monarch butteries. The butterflies lay their eggs exclusively on Milkweed plants, creating an opportunity for us to plant Monarch habitat!

If you live in California, we suggest the native Narrowleaf Milkweed.

We recommend planting only milkweed plant that is native to your area.  Each region is going to have milkweed specific to its area - except the Pacific Northwest.

Reasons why planting non-native milkweed is detrimental to the Monarchs:

  • In warmer regions, where milkweed does not die back in the winter, a build-up of a debilitating protozoan parasite (Ophryocystis elektroscirrha or OE) that infects monarchs can occur.
  • Non-native milkweed presence in the fall could cause migrating monarchs to break diapause (a temporary non-reproductive state) and lay eggs instead of completing their migration to Mexico.
  • Reseeding (and invasion) of non-native milkweed species


This wildflower is low maintenance, easy to grow and propagate. Known for their beautiful colors ranging in white to pink and deep purple, the Milkweed brings joy and life to every garden! Exuding a delicious vanilla scent, the milkweed also attracts other pollinators while bloom from June - August.  Monarchs will lay their eggs  on the milkweed and caterpillars will emerge around September, while the plant is creating its seed pods.  During this time, the caterpillar will devour the all the leafy matter of the plant and leave the seed pod alone.  It is imperative to allow the caterpillar to attain the nourishment it needs, while in the larvae stage. In 2–3 weeks, it grows to about 2,700 times its birth weight

 

It is very important to plant locally native milkweed species.  Please learn which milkweeds are native to your region and consult this milkweed range maps from the Biota of North America Program’s (BONAP) North American Plant Atlas.

      Map of states that we recommend planting Common Milkweed.

      Grows well in most soil types - preferring well draining soil.  The Common Milkweed makes it an excellent border plant.  Can tolerate drought and is deer resistant.  Once planted this beneficial plant will quickly spread - if weeding out, consider replanting it somewhere else in your yard or giving to a friend.   Easily spreads via seed and rhizomes.  Plant forms small to large clones. A great way to help spread Common Milkweed is by cutting and transplanted the rhizomes in early spring.
