Large Coneflower is a dramatic perennial native to North American prairies, rising 5 to 7 feet tall with bold, paddle-shaped bluish-green foliage that anchors the garden even before flowers appear. In June and July, sturdy flower stalks bear bright yellow-rayed coneflowers up to 3 inches across, each with slightly drooping petals surrounding a distinctive dark brown cone that can reach 2 to 6 inches high. Hardy in zones 4 through 9, this coarse-textured plant thrives in full sun with moderate water and low maintenance, tolerating drought and heat once established. The flowers cut beautifully fresh and dry exceptionally well for arrangements, while birds and butterflies flock to the tall, dark cones. It's a natural choice for prairie gardens and wild areas where it will self-seed and naturalize.

The sheer architectural presence of this plant sets it apart in the summer garden. Those enormous basal leaves, reaching 24 inches long, create a lush foundation long before the flowers arrive, while the flower stalks stretch skyward with an almost architectural elegance. The interplay between the cheerful yellow rays and those commanding dark brown cones makes every bloom feel substantial and sculptural. This is a coneflower that commands attention rather than blending in, yet it asks almost nothing in return.
Large Coneflower shines as a back-of-the-border statement plant in cottage gardens and naturalized prairie plantings. The tall, sturdy flower stalks are exceptional for cutting, offering long-lasting color and interesting texture in fresh arrangements. Dried flowers retain their character beautifully, making them a favorite for dried bouquets and winter arrangements. In wild and naturalized settings, this plant fills the ecological role of a nectar and seed source, supporting birds and pollinators throughout the growing season.

Start seeds indoors 4 to 6 weeks before your last spring frost at a germination temperature of 65 to 75 degrees Fahrenheit. Transplant seedlings outdoors after the danger of frost has passed.
Harden off seedlings gradually over 7 to 10 days before moving them to their permanent location. Space plants 18 to 30 inches apart (some sources suggest up to 36 to 48 inches for larger specimens). Plant after the last frost date when soil has warmed.
Direct sow seeds in spring after the last frost, pressing them lightly into soil and keeping consistently moist until germination occurs.
For fresh-cut flowers, harvest stems early in the morning after the dew has dried but before the heat of the day intensifies. Cut when the yellow ray petals have fully unfurled and the central cone is visible but still firm. For dried flowers, allow blooms to mature fully on the plant, cut them when the rays have begun to reflex slightly downward, then hang bundles upside down in a warm, dry location out of direct sun for 2 to 3 weeks until completely papery.
Little pruning is necessary for Large Coneflower. Remove spent flower heads in late summer if you wish to tidy the plant or prevent excessive self-seeding, though allowing some flowers to remain will reward you with self-sown seedlings the following season. Cut back to the base in late fall or early spring as new growth emerges.
