Coreopsis 'Incredible! Swirl'

Coreopsis hyb.
Creamy to pure white flowers have free-form brushstrokes of dark cherry near the centers. A billowing form adds an informal meadowy look to summer gardens, and as a native, they bring in the pollinators. Deadhead for a very long season of bloom.

PLACEMENT & CULTIVATION
Native coreopsis furnishes meadow gardens and old-fashioned cottage and rock gardens with prairie style, its thin, wiry stems holding firm to the breeze-tossed dancing flowers. It is also useful in vegetable gardens, attracting beneficial insects and pollinators while also being deer-resistant. Taller plants may need an underpinning of support in very windy conditions. After the first flush of bloom, shear the plant by one-third to promote a later full flowering or deadhead regularly.
