In an HOA neighborhood

Poison-milkweed takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.

  • Name includes 'poison' which raises concerns
  • Can appear weedy or wild in formal settings
  • Dies back completely in winter leaving bare spots
