Hot summer color!

Want a low-maintenance perennial that can take the summer heat? ‘Mercury Rising’ threadleaf coreopsis doesn’t set seed, so you won’t have to deadhead to get continuous blooms. Its rich red flowers don’t fade in the sun, either. Instead, they get larger as they mature, growing up to 2 inches wide. Give disease-resistant ‘Mercury Rising’ a place near the front of the border, and you’ll draw lots of butterflies to an easy-to-see spot!
