The Plant:

  • An herbaceous perennial, 2-3 feet tall. Plants have a clumplike habit, with erect flower stems.

The Leaves:

  • opposite
  • few actually paired
  • some in tufts
  • mostly on lower half of stem
  • entire

  • some with 2 basal prongs

The Stem:

  • erect

The Flowers:

  • Eight yellow ray flowers with four deep lobes at the tips. Scape-like flower stalks.

The Fruits:

  • dark brown
  • winged
  • curved or semi-circular

The Habitat:

  • poor soils
  • dry sandy
  • roadsides

Dispersal:

  • wind and water dispersed seeds
  • also through dumping of garden waste and contaminated soil

Key ID Features:

  • yellow daisy-like flower
  • 8 petals with 4 lobes at tips

Similar Species:

  • Large flowered coreopsis (Coreopsis graniflora) is very similar but is taller (about 3 feet) and has leaves the entire length of the stem.

Notes:

  • While this species is native to central and southeastern United States, it is not native to the New England area. Due to its dense clumping habit and prolific self-seeding it can crowd out native plants and reduce the success rate of native seed germination. It is commonly planted in yards and gardens, but care should be taken as the plant easily naturalizes as an invasive self-seeder. The wind and water spread seeds are the primary cause for dispersal of this plant, but contaminated garden soil and garden waste dumping additionally contribute to its wide range establishment.
  • On Nantucket, this species is still heavily planted, and is escaping from cultivation. Seems to persist in grasslands but not visibly outcompeting the native flora.
