The 7-9" single flowers of 'Rocket's Red Glare' glow with a red starburst with white veins on a blue background, giving a red, white and blue effect. The flowers open in a pinwheel shape that flattens to typical hibiscus form. The medium-sized bush is a prolific bloomer. 'Rocket's Red Glare' is the offspring of 'Rainbow Christie' and 'Edna Bogart.' Released from HVH in 2008.
