Large-flowered Coreopsis
Coreopsis grandiflora
Plant Details:
Plant Type: Perennial
Plant Family: Asteraceae
Plant Description: Eye-catching large yellow flowers make this wildflower a mainstay in informal perennial gardens and meadows. Daisy-like disks of large, notched petals bloom for most of the summer if deadheaded. The thin green leaves grow along the stems, forming loose, airy mounds. Attracts a variety of pollinators and beneficial insects. Individual plants may not come back every year, but it reliably re-seeds. Many of the interesting cultivars do not stay true to seed, resulting in generic offspring. Thrives in poor soil and full sun.
Maintenance:
Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
Special Considerations: This plant will reseed and spread readily. To avoid unwanted seedlings, promptly remove spent flowers.
