Plant Type: Perennials

Huge, dinner plate sized flowers sit atop robust, shrub-like plants from mid to late summer. 'Blue River II' is especially long-blooming. Each successive spring will bring larger flowers. This variety produces pure white flowers with no contrasting eye. The foliage of 'Blue River II' bears a hint of blue, giving the plant an overall cooling effect, great for those hot summer days in the garden. It's hard to believe this tropical-looking beauty is hardy to zone 4!

 


Growing & Maintenance Tips:

Hibiscus love the sun and need moist, well-drained soil. Keeping these plants watered will result in larger flowers and lush foliage. Deadheading may prolong the bloom period. It is best to plant Hibiscus in the garden before the heat of the summer arrives, and should be heavily mulched the first winter. In spring, cut back any remaining stems before new growth appears. Be advised that this species is always one of the last to emerge in spring. Its vigorous growth rate more than makes up for this late start, however. Japanese beetles find these plants especially delicious.
