Early Large Flowered, Group 2.
Violet. Average diameter 5". Medium to large, double bloom form. Late spring to early summer, early autumn to midautumn.
Height of 6' 7" to 9' 10" (200 to 300 cm).
USDA zone 5a and warmer. Suitable for growing in a container. It blooms on the previous year's growth, so resist the urge to prune it in early spring.
