Large, creamy white flowers have a small purple fleck at the base of the petals and the color radiates out to the edge in cooler weather. Blossoms in varying shades of white and purple are often in bloom at the same time, creating a striking look. Sturdy, well-branched plants bloom from June to October. Very easy to grow and drought resistant once established, ‘Star Cluster,’ like the other members of the Big Bang Series thrives in a wide range of growing conditions in beds and borders. Plants reach a height of 24 to 30 inches with a 24-inch spread and are hardy to Zone 5.
