Care Instructions
Thrives in average to lean, well-drained soils. Water regularly in first growing season to establish root system. Reduce frequency once established in landscape; water containers when soil surface is dry. Remove spent flowers for a neat appearance. Cut back in fall after flowering. Fertilize in early spring.
History
This selection is a North American native cultivar from breeder Darrell Probst of central Massachusetts, and is the result of ten years of hybridizing hardy Coreopsis. These improved perennial forms are evaluated for hardiness, extended duration of flowering, distinctive flower forms, improved disease resistance, vigor and improved plant habit. The red color of 'Mercury Rising' comes from Coreopsis rosea, a hardy perennial, not Coreopsis tinctoria, which is an annual and the parent of other red-colored varieties which are neither hardy in zone 5 nor long-lived perennials in warmer zones. C. 'Mercury Rising' is truly perennial, and has survived sub-zero temperatures and thrived in Zone 5 for three years.
