Shrubby looking biennial or short-lived perennial that reseed regularly. Airy habitus with hundreds of small, deep gold flowers bloom! Heat, humidity and some drought tolerant plant. Adaptable to many types of soil and tolerant to some shade too. Georgia Gold Medal Winner in 1997. Highly recommended plant for home landscaping.

Easy to grow plant that will bring lots of butterflies and bees. A native wildflower that is an excellent in naturalized areas, wildflower meadows, prairies, cottage gardens, native plant gardens, pollinator gardens or butterfly gardens, but also in regular flower beds.

The best combination are with purple or blue flower of Aster novae-angliae, Aster novi-belgii, Aster laevis and other blue asters, Eupatorium coelestinum (Conoclinum), Eupatorium purpureum, Vernonia. Other good combination include Echinacea purpuea, Phlox paniculata, or grasses like Panicum virgatum. Good companions are annual sages (Salvia – with blue flowers), Salvia uliginosa, Verbena bonariensis. Looks very good with grasses with dry seed heads already like Stipa gigantea or Descchampsia caespitosa.
