Culture Notes The Hibiscus plant produces the largest flowers of any perennial. It not only grows perfectly in average garden soil, but also does well in moist, windy areas. Cut back stems in early spring. Propagate by soft-wood cuttings in the summer or hard-wood cuttings in the fall. Plants go well with: Helianthus, Rudbeckia, Echinacea, and Malva. Although the Hibiscus plant is tall, the need for staking is rare. Shrublike in appearance, these plants do die back to ground level during the winter months. With regular pruning, it can be used as a hedge or specimen plant.
The buds of 'Sweet Caroline' have an unusual rosebud shape. Its gorgeous pink flowers are 6-8" in diameter, irregularly ruffled and display deeper pink veins as well as a deeper pink eyezone. Asexual propagation of this plant is prohibited.
