The Blue Hibiscus is a fast growing evergreen shrub. This shrub loves full sun and is drought tolerant. It does require regular water during the summer but does not like to be watered much in the winter and it is very cold hardy. The Blue Hibiscus has deep green leaves with lilac colored flowers that resemble the original Hibiscus. It blooms on and off throughout the year and grows up to 6 feet high and wide. For best results regular pruning is necessary.
