SUNNY DAYS 'Ruby' Coneflower

Sunny Days™ Ruby is an upright Echinacea selection with stout stems and large, double ruby-red flowers. Terra Nova describes the flowers as claret-ruby with little color shift and lists a July–October bloom season, while the cultivar patent documents USDA zones 4–9, an 18-inch foliage height, a 24-inch flowering height, and an 80-centimeter spread. [Terra Nova’s cultivar profile](https://www.terranovanurseries.com/product/echinacea-sunny-days-ruby/) and the [USPP33437 patent](https://patents.google.com/patent/USPP33437P2/en) identify the same selection as ‘TNECHSDR’. ## Form and Placement The upright clump carries oversized, double blooms on strong stems. Use it in a sunny perennial border or cut-flower planting, allowing about 24–32 inches of spread; the breeder lists the wider mature spread in its patent description. The flowers attract pollinators and hummingbirds, and the cultivar profile lists average soil and water needs. ## Maintenance Plant in full sun and average garden soil. Follow the breeder’s average-moisture guidance, avoiding prolonged saturation around the crown.
