Sweet Tart Coreopsis

Fast-growing under ideal conditions. Plants typically reach full size within their first growing season, forming mounds approximately 15–18 inches tall and wide.

Highly attractive to pollinators such as bees and butterflies. Birds may feed on mature seed heads if left on the plant. Generally resistant to deer and rabbits.

Blooms from early summer through fall. Herbaceous perennial that dies back to the ground in winter and re-emerges in spring. Hardy in USDA Zones 5–9.

Features finely dissected, thread-like, bright green leaves that form a dense, bushy mound. The delicate foliage provides a soft backdrop for the vibrant flowers.

Produces an abundance of single, raspberry pink flowers that lighten toward the yellow centers. Each bloom measures approximately 1.5 inches across and is held on slender stems above the foliage.

Deadhead spent blooms regularly to encourage continuous flowering. A light shearing after the first flush of blooms can promote a second bloom cycle. In late fall, cut back the plant to a few inches above ground level to prepare for winter dormancy.

Moderate water needs during establishment. Once established, it is drought tolerant and prefers soil to dry slightly between waterings. Overwatering can lead to root rot, especially in poorly drained soils.

Requires full sun for optimal performance. Provide at least 6 hours of direct sunlight daily. Inadequate light may result in reduced flowering and a leggy appearance.

Flowers can be harvested for fresh bouquets. Cut in the morning when blooms are fully open. While not a traditional cut flower, it adds a cheerful touch to informal arrangements.

Fertilize lightly in early spring with a balanced, slow-release fertilizer (e.g., 10-10-10). Over-fertilization can lead to excessive foliage growth at the expense of blooms.

Attracts a variety of pollinators, including bees and butterflies, due to its abundant nectar and accessible flower structure.

Pairs well with other sun-loving, drought-tolerant perennials such as Echinacea, Salvia, Gaillardia, and ornamental grasses. These combinations enhance color contrast and support pollinator activity.
