Common lousewort is a low-growing native wildflower that produces distinctive hooded yellow or reddish flowers in early spring. This compact perennial forms small clumps with deeply cut, fern-like foliage and typically grows 4-12 inches tall. It thrives in partial shade with moderate moisture and goes dormant in summer.

In an HOA neighborhood

Common Lousewort 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.

  • Unusual name creates negative perception
  • Looks very wild and unmanicured
  • Goes completely dormant leaving bare spots

Wildlife value

The tubular flowers provide nectar for native bees and butterflies during the early spring pollinator season. This plant is particularly valuable because it blooms when few other native flowers are available.

Native range data from the USDA PLANTS Database and regional native plant society lists. Pollinator and host plant associations compiled from GBIF, iNaturalist, and published ecological literature.
