Echinacea tennesseensis

Echinacea tennesseensis

Echinacea tennesseensis is the Tennessee coneflower native to cedar glades near Nashville. It stands out for upturned, east-facing rays around a coppery cone. It performs best in full sun and thin, calcareous, well-drained soils. It is hardy mainly in Zones 5 to 6 and prefers drier winters. It blooms from June into August and brings a compact habit to beds and borders. It has recovered in the wild and was removed from the U.S. endangered list in 2011.

How it differs

  • Rays tend to face upward and often orient east in the garden.
  • More compact habit than many purple coneflowers.
  • Prefers very well-drained, limey soils typical of cedar glades.
  • Hardiness range is narrower than common purple coneflower.

Strengths

  • Distinctive flower posture for design contrast.
  • Tidy size for smaller beds and front-of-border use.
  • Good heat tolerance in sunny, well-drained sites.
  • Supports pollinators and provides seed for birds.

Care in one minute

  • Site in full sun with excellent drainage; gravelly or rocky soils suit it.
  • Water to establish; then water deeply only during extended dry spells.
  • Avoid heavy mulches and winter-wet conditions around crowns.
  • Deadhead to tidy or leave seedheads to feed finches.
  • Do not overfertilize; lean soils keep stems upright.

Watch‑outs

  • Overly rich or wet soils can cause flop or decline.
  • Aster yellows can affect growth in mid-summer.
  • Not reliably hardy where winters are very cold and wet.

Best uses (tags)
