Yellow Fully Double Coreopsis is a dwarf, double-petaled tickseed that brings native wildflower charm to any garden. This early bloomer reaches just 12 to 14 inches tall and produces masses of cheerful yellow flowers that attract pollinators from early summer onward. Hardy in zones 4 through 9, it thrives in full sun and adapts remarkably well to variable soil conditions, flowering within 60 to 90 days of planting. Whether nestled in meadows, wildflower stands, formal borders, or containers, this heirloom coreopsis proves that big character comes in small packages.

The fully double petals set this variety apart from single-flowered coreopsis, creating dense, button-like blooms that look almost like tiny pom-poms. Its dwarf stature makes it an exceptional choice for front-of-border placement and container gardens, while its adaptability to poor soils and drought conditions means it thrives where other plants struggle. As a pollinator magnet and early season bloomer, it extends the nectar season in spring gardens and provides sustained color throughout the growing period.
Yellow Fully Double Coreopsis shines in mixed flower borders, wildflower meadows, and pollinator gardens where its prolific blooms support bees and butterflies. Its compact, tidy growth habit and long flowering period make it particularly valuable for container plantings, rock gardens, and edging applications where height control matters. The fully double flowers also work beautifully as cut flowers for small arrangements.

Start seeds indoors 6 to 8 weeks before your last spring frost. Sow seeds on moist soil, press lightly without covering (they need light to germinate), and maintain temperatures between 50 and 75 degrees Fahrenheit. Seeds typically sprout within 10 to 21 days. Harden off seedlings over 7 to 10 days before transplanting outdoors after all frost danger has passed.
Transplant hardened-off seedlings outdoors after the last spring frost when soil temperatures have warmed. Space plants 10 inches apart in full sun locations. Water gently after transplanting and keep soil evenly moist for the first few weeks until plants establish.
Direct sow seeds after the last spring frost in areas with warm growing seasons. Press seeds lightly into prepared soil without burying them, as light exposure aids germination. Water gently and keep soil moist until seedlings are established.
Deadhead spent flowers regularly throughout the growing season to encourage continuous blooming and maintain the compact, tidy appearance this dwarf variety is known for. Cut back or shear plants lightly after the first flush of flowers fades to promote a second wave of blooms. In fall after flowering ceases, you may cut plants back to ground level for winter cleanup.
