Its hard to believe that this
tropical looking plant is hardy to zone 4! Enormous, dinner plate sized white flowers
explode from robust, shrub-like plants. Blooms begin to appear in mid summer and
continue to unfurl right up until the first frost. Bloom River II is continued to be
a heavy bloomer and with age the flowers get larger and larger. The pure white
flowers of this Hardy Hibiscus have no contrasting eye, making them perfect for the all
white or moonlight garden. The leaves of Blue River II have a subtle hint of blue in
them creating a very elegant backdrop for the large white flowers. Introduced by Dr.
Harold F. Winters who found this beautiful perennial growing along the bank of the Blue
River in southern Oklahoma - hence the name. Hibiscus are true sun lovers and need a rich
moist soil. While Hibiscus will grow in dryer soils - providing the plants with
adequate water will reward you with larger blooms and lush foliage. Read our garden
guide Planting Hibiscus for more
details. Prune back any remaining stems in spring before new growth appears.

Hibiscus guide.
