'Blue River II' Hardy Hibiscus
Dinner-plate size white blooms give this hardy hibiscus a breathtaking quality from July to September. Like all hardy hibiscus, 'Blue River II' performs best when soil stays consistently moist and full sun bathes the plant. Cut plants back to 3 to 4 inches in late fall. This hibiscus is hardy in zones 4 to 9; provide winter protection in coldest zones.
