SOMBRERO® Tres Amigos Coneflower

SOMBRERO® Tres Amigos is the named Echinacea selection Balsomtresgo, a compact, upright coneflower with flowers that open peachy-coral, age to rose, and fade to burgundy. Darwin Perennials lists it in the SOMBRERO® series and identifies the cultivar as Balsomtresgo. [Breeder profile](https://www.darwinperennials.com/Products/Details/?phid=024102187040136) ## Garden placement The breeder lists a height of 18–20 inches, spread of 22–24 inches, and hardiness in USDA zones 4b–9b. Flowers appear in late spring and summer; the plant grows upright in full sun. Its compact stature suits the front or middle of a sunny perennial bed, and the breeder recommends it for a 2.5-quart container. ## Seasonal display The three color stages can overlap on one plant, giving the flowers a changing coral, rose, and burgundy display rather than a single fixed shade. The Chicago Botanic Garden trial observed uniform, bushy plants and flowers that held the different color stages together through the season.

Removing faded flowers can keep the display tidy; leaving some seed heads offers birds a food source, a tradeoff noted in the coneflower trial.
