Coreopsis verticillata Coreopsis are long-time cherished perennials for their beauty, reliability, extended bloom time and durability. Crème Caramel is an exceptional variety with very fine, narrow foliage and masses of pollinator-attracting blooms. Drought and heat-tolerant plants reach a compact, dense mound 18 inches tall and 24 inches wide. Late spring and throughout the summer, the continuous show of blooms offers a range of shades from copper, fading to apricot and finally pale peach with time. Hardy in zones 5-9.
