This cultivar is celebrated for its profuse clusters of soft, lavender-purple flowers. The crinkled blooms appear in abundance from early summer and, most notably, continue with new flushes of flowers well into the fall. The series name Enduring Summer highlights its exceptional, long bloom time. The leaves are a glossy, dark green throughout the growing season. In the fall, they turn attractive shades of orange-red, adding a final burst of color before the leaves drop.
