The threadleaf foliage of coreopsis verticillata makes a nice edging plant for this garden of soft colors. While Coreopsis 'Zagreb' is a bolder yellow than the popular 'Moonbeam', it's a much hardier plant and it likes to spread out. Butterflies look for large swaths of color. They want to know it's worth their time to fly down and land.
The threadleaf coreopsis are very easy growing. They set an abundance of flower buds along their wispy flower stems. It's easiest to let the plants bloom themselves out and then shear back the whole plant by 1/3, rather than trying to deadhead. The plants will rally and rebloom in a matter of a couple of weeks.
