The Plant:

  • A shrubby, herbaceous perennial, 3-6 feet tall.

The Leaves:

  • compound leaf with three oblong leaflets, 1 inches long
  • wedge-shaped leaf bases
  • short petioles
  • gray-green
  • dense, flat hairs
  • leaves rounded with small pointed tip

The Stem:

  • branching
  • ascending stems
  • numerous
  • tall

The Flowers:

  • Creamy white, purple streaked, short, five-petaled flowers growing in solitary or in clusters of up to four. Blooms from July to October.

  • pond borders, swamps, marshes
  • open woods and disturbed areas

Dispersal:

  • seeds are animal dispersed
  • possibly included in wildflower seed packets

Key ID Features:

  • cream colored flowers with purple veins
  • branching stems
  • wedge-shaped leaf bases
  • stem hairs flattened to the stem

Similar Species:

  • Round-headed bush clover (Lespedeza capitata) and Hairy bush clover (L. hirta) have similar cream-colored or yellowish flowers. Only Sericea lespedeza has two broad violet streaks on the inside of the upper petals of the flowers. It also has stem hairs that are flattened to the stem, while the other species have stem hairs that are spreading.

Notes:

  • Sericea lespedeza can crowd native plants as it grows into dense stands and it also creates a large seed bank in the soil. Rapid seed production and dispersal allow for extensive growth and reproduction and it is toxic or unpalatable to most herbivores.
