Echinacea paradoxa

Echinacea paradoxa

Echinacea paradoxa is the yellow coneflower that breaks the purple color rule in this genus. It stands out for bright yellow rays and a bold cone that show well in full sun. It performs best in well-drained, lean soils with regular sun and summer heat. It is hardy in Zones 5 to 8 and dislikes winter-wet conditions. It works in native plantings, meadow borders, and mixed sunny beds. It attracts pollinators and leaves ornamental seedheads for birds.

How it differs

  • Only Echinacea species with naturally yellow rays.
  • Prefers hotter, glade and prairie conditions of the Ozarks.
  • Similar height to many purple forms but with a brighter color impact.
  • Less cold-hardy than some purple species in Zone 3 to 4 climates.

Strengths

  • Striking color contrast in mixed sun borders.
  • Tolerates drought once established.
  • Low maintenance in lean, well-drained soils.
  • Seedheads add fall and winter structure.

Care in one minute

  • Grow in full sun on well-drained soil; avoid soggy sites.
  • Water to establish; then water deeply only during extended drought.
  • Do not overfertilize; excess nitrogen softens growth.
  • Deadhead to tidy or leave some seedheads for birds.
  • Mulch lightly and pull back from the crown going into winter.

Watch‑outs

  • Winter-wet soils can cause crown loss.
  • Partial shade reduces flowering and color intensity.
  • Standard coneflower issues include aster yellows and leaf spots.
