We have been searching for a tall yellow cosmos and finally found it. We can’t wait to share it with our fellow gardeners. Gentle flowers sway in the breeze, tempting birds, butterflies and pollinators alike. We had lots of fun watching the finches dance among the blossoms just outside our door. Petals start out a delicate light yellow and as the plant grows and the season moves on they deepen to a rich butter color. Grows to 4 feet.
