Coreopsis verticillata ‘Sweet Marmalade’

Threadleaf Coreopsis

USDA Zone: 5-9

Plant number: 1.165.270

Threadleaf Coreopsis forms a spreading clump of very delicate, ferny foliage and is native to the eastern United States, east of the Mississippi River, growing in dry, sunny locations where it is tolerant of drought, poor soil, heat and neglect. This new introduction bears loads of flowers that open deep orange then lighten to a soft apricot-yellow as the season progresses. Blooming begins in summer and lasts into the fall. Attractive to butterflies. Excellent in the middle of the sunny border, in mixed containers and as a cut flower. Clipping off faded flowers will encourage buds to form all season. Tolerant of hot, dry sites, once established. Easily divided in early spring. Sport of C. ‘Creme Brulee’. From Blooms of Bressingham® by way of Yohei Hosogai of Nichien Company, Japan. USPP#20702: unlicensed propagation prohibited. Registered with COPF.
