In 2001, we picked up this gem in the Florida panhandle where it resides, and have been so impressed with it since that we had to share. Coreopsis gladiata has been thoroughly confused by herbarium botanists (folks who identify only dead, smashed plants) to the point that some think it's the same as Coreopsis helianthoides (a stoloniferous, glossy leaf species), and others think it's an annual. Coreopsis gladiata is a tight clumping perennial species composed of upright stems and thick, hairy, 3" long, linear leaves. The 18" wide clumps are topped, starting in mid-October, with thin stalks of bright golden daisies to 30" tall. Despite being native in moist sand, we grow them with yuccas where they thrive!
