Firefly, also known as Tickseed, Coreopsis Verticillata, or Thread Leaf Coreopsis, is a perennial flowering plant native to North America. Terra Nova developed this hybrid variety for its mildew resistance and cold-hardiness. This plant offers a compact mounding habit of 10-12" tall and 16" wide, with dense, dainty foliage and yellow and red flowers that bloom from June through October. Perennial in zone 5-10, Firefly attracts pollinators and flourishes in full sun with minimal water. Cheery flowers offer long-lasting bright color without deadheading. Coreopsis is well-suited to landscape borders, mixed garden beds, and containers. Grow this plant alongside Castello Pompon Yellow for a distinctive color combination.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
