Originating in the Southeastern United States, Large-Flower Tickseed has made its way up to the Northeast as a popular wildflower. It is generally pretty hardy, tolerating low nutrient and rocky soil conditions. With its bright golden-yellow, daisy-like flowers that bloom from late spring to early summer, it adds a vibrant burst of color to your garden. Coreopsis grandiflora is a hardy and low-maintenance plant, thriving in a variety of soil types. It’s well-suited for both sunny and partially shaded areas, making it versatile in many garden settings. The plant’s deep green, finely textured foliage remains attractive even when it’s not in bloom, providing year-round visual interest.

While not native to New Jersey, Large-Flower Tickseed still supports a variety of pollinators, including various bee species, butterflies, and birds. Its extended bloom period ensures a consistent source of nectar for these beneficial insects throughout the summer. However, different cultivars may affect the number of pollinators these flowers attract. A cultivar with different color flower or structure may be unable to support the pollinators that depend on the original native species.
