My 2nd favorite perennial ever. I've had the same one at my folks house for 7 years and she does NOT have a green thumb. Blooms from May til Halloween, no joke! This is Early Sunrise Coreopsis. The more sun, the better! Zone 3-9
Yarrow / ATTRACTS: Orioles. Plant with Red Oak Tree which attracts Monarch Butterflies. (Tufted -Achillea Lewisii is the best). Great for attracting bugs which are important to nestlings in the Spring. Plant in roadside ditches. NEVER PLANT "A. MILLEFOLIUM" Will get out of control and take over your entire yard!!!!
Power Perennials: Plants That Thrive No Matter What
Coreopsis: Hot, dry weather won’t stop Coreopsis from flowering all summer long. This American native is one of the most reliable perennials you can grow. The plants produce large quantities of yellow, orange, pink, white, red, or bicolored blooms.
