Early Sunrise, an All-America Selections Gold Medal winner, is cold-tolerant, hardy to zone 4, and heat-tolerant to zone 9. It is also drought-tolerant and tough enough to be planted street-side. This is one of the best perennials for the beginning gardener, guaranteeing a green thumb.
Set out nursery-grown transplants in early spring after the last frost at the same depth they were growing in the container, spacing plants 12 to 15 inches apart.

One key cultural technique with the Early Sunrise coreopsis is to remove old flowers. This keeps the plant tidy and the blooms producing, and reduces the possibility of old flowers getting pathogens that can infect the rest of the plant. Seeds saved from one plant will not produce the same type. Early Sunrise probably will need dividing by the third year to keep the quality of the plant at its best. Clumps may be divided in spring or fall.
