Early Sunrise All-America Selections Winner, Fleuroselect Gold Medal

The first Coreopsis on the shelf! There’s early…and then there’s Double the Sun! This bright variety is 2 to 3 weeks earlier than our Early Sunrise and other comparable varieties. In Summer, it finishes 1 to 2 weeks before the rest. This favourite perennial class can be on store shelves before any other compact, semi-double yellow Coreopsis.
