Faits intéressants

Gray-headed coneflower is a tall, cheerful prairie perennial with bright yellow petals surrounding a prominent brown central cone. It adds height and movement to native gardens. It naturally grows in prairies, meadows, open woodlands, and roadsides. Its tall stems make it excellent for meadow-style plantings and sunny borders.

Gray-headed Coneflower is drought tolerant once established. It makes an excellent cut flower. It may flop in very rich soils so avoid over-fertilizing. It is best planted in groups for impact.
