Plant Sale Text: Green-head coneflower is closely related to the black-eyed-susan, and bears dozens of 2-3 inch clear yellow flowers. Its graceful pendulous petals radiate from a gumdrop shaped greenish-yellow central disk. This southeastern native perennial is commonly found growing in wet areas. Green-head coneflower is very adaptable and will also thrive under the conditions in the average garden. 1995 N.C. Wildflower of the Year.
Bloom Table Text: This magnificent mid-summer bloomer, most commonly called Cut-leaf Coneflower, is a favorite garden addition because of itâ€™s ability to flower in the shade as well as the sun. Itâ€™s nectar attracts butterflies and when it goes to seed it become a favorite food of the Common Goldfinch. Cutleaf Coneflower is a host plant for the caterpillars of the butterfly, Silvery Checkerspot. Ranging from 3-8 feet tall, with average soils and water requirements, it blooms for the whole month of August. This Rudbeckia naturalizes easily by seed, although deadheading or adding to a bouquet will encourage fall blooming. This native coneflower is a welcome addition to any garden.
