The deliciously colored maroon-brown leaves contrast nicely with neighboring plants through the season. Pure white flowerheads bloom in midsummer and stay open well into autumn.

The leaves of this hardy hibiscus are copper-red on top and orange-red underneath. Ruffly white to pale pink flowers, 10 to 12 inches across with a distinct red eye, bloom from midsummer to mid-fall with deadheading. Because the top of 'Kopper King' dies back to the ground in autumn and is late to break dormancy in the spring, interplant it with spring bulbs and overplant it with winter annuals not only to provide year-round color but also to allow the hibiscus to grow undisturbed.

Though relatively pest-free, 'Crimson Curls' heuchera needs constant moisture to look its best. The white flowers contrast nicely with the ruby-colored foliage that deepens in direct sun, and the late-spring flowering repeats by late summer if deadheaded. Due to its constant-moisture requirement, don't grow 'Crimson Curls' in a pot. Use it massed along a walkway or in a woodland setting.

Rows of white flowers dangle above the fern-like foliage, opening in April and continuing intermittently until October.
