100% survival in the 2014-2015 winter at the University of Minnesota Perennial Flower Trial (with very little snow cover!). Given 4/5 points in trials at Disneyworld in Florida warm season 2016.
Grow with 55 – 60° F nights and 60 – 70° F days. Pinch at transplanting. Obligate Long Day plant. Provide night interruption or day-length extension to force flowering under natural short days. Supplemental lighting during cloudy days has proven beneficial for flower production. For highest quality, bring in liners in fall to bulk for early spring sales.
Perfectly formed compact mounds of dense thread-like foliage are blanketed with startling, yellow and red bi-colored flowers. Underneath the sheer beauty of this plant is the rock hardiness of Coreopsis verticillata breeding. Zone 5 hardy and super easy to grow with the added feature of powdery mildew resistance! This is definitely a plant for the front of the border or in a mixed container. Versatile, easy, and just fun!
