Coreopsis ‘Firefly’

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!

Grower Notes 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.
