This is one of our earliest blooming milkweeds, which is great for early summer butterflies. Although not an aggressive spreader, it can form a colony, so it is not recommended for small gardens. Its growth habit makes it a great plant for erosion control. Its height of 3' makes it great for the middle of a border.

Maintenance: To control self sowing remove the seed heads.

Benefits: Host plant for monarch caterpillars and several moth and insect species. Nectar and pollen source. Attracts hummingbirds, bees, butterflies, specialized bees, and predatory insects. Drought tolerant.

Fun Facts: Milky sap may cause a rash and eye irritation. If eaten, it can cause stomach upset, nausea, weakness, and abdominal pain. Sap contains a cardiac glycoside but it's a low poison plant.

Companion Plants: Monarda punctata (spotted bee balm), Echinacea purpurea (purple coneflower), Pycnanthemum tenuifolium (threadleaf mountain mint), Coreopsis verticillata (threadleaf tickseed), Rudbeckia fulgida var fulgida (orange coneflower)
