Double The Sun Coreopsis
Coreopsis grandiflora 'Double the Sun'Double the Sun Coreopsis is a cheerful, long-blooming perennial prized for its fully double, golden-yellow flowers that brighten the garden from late spring through summer.

The abundant blossoms are produced continuously over an extended season, providing reliable color and making this cultivar an eye-catching addition to borders, pollinator gardens, and container plantings.
