Coreopsis flowers gently sway in the lightest breeze, appearing to almost float above the delicate foliage. Wildflowers, like this heirloom, are easy to grow and don’t need special care, other than water, although moderately drought and heat tolerant, too. Butterflies and bees delight in the nectar, and songbirds seek out the seeds in fall and winter. Coreopsis is also known as tickseed. Often reseeds.
