'Three-Ring Circus' blooms with vivid, ruffly 8-10" flowers in 3 rings of maroon, pink, and yellow. It is the offspring of the well known 'Rainbow Christie' and an unnamed but very large HVH seedling that died after we made this cross. Fortunately, 'Three-Ring Circus' inherited the large flower genes. It is a good bloomer, and the bush matures into a large and strong bush. Released from HVH in 2005.
