Cercis canadensis 'Whitewater'

'Whitewater' redbud is a deciduous woody shrub or tree in the Fabaceae (bean) family. The parent plant is native to eastern and central North America. This cultivar from Dr. Dennis Werner of North Carolina State University has a weeping habit and grows to 6 feet tall and 2 to 3 feet wide. The genus name Cercis comes from the Greek word kerkis, which means weaver's shuttle, referring to the fact that the seed pod resembles the size and shape of a weaver's shuttle used to move thread back and forth on a loom. 

This plant requires full sun to partial shade. It is at its best in full sun but benefits from some afternoon shade in hot climates. It prefers to grow in average to moist conditions and shouldn't be allowed to dry out. It is not particular as to soil type or pH and is highly tolerant of urban pollution, even thriving in inner city environments. Plant it in a relatively sheltered location and consider applying a thick layer of mulch around the root zone in winter to protect it in exposed locations or colder microclimates. Maintenance is low; any pruning should be accomplished after the flowers have bloomed.

Deep rose-purple, pea-shaped flowers bloom in April and May and are displayed on the bare branches. The flowers give way to heart-shaped leaves, which emerge mostly white with green flecks and mature to mostly green with white flecks. Its weeping habit is an exciting addition to the bright variegated foliage.

‘Whitewater’ is versatile in the landscape. With this stunning combination of features, it is perfect as an accent or specimen plant, although it is also suitable in a border, as a foundation or mass planting to provide screening, or near the street. Its relatively small size also lends it to small spaces, patios, ponds, walkways, and containers. Alternatively, use it in a pollinator, butterfly, cottage, or rock garden.

Insects, Diseases, and Other Plant Problems: Some insects affecting this tree are twig borer, treehoppers, caterpillars, scales, and leafhoppers. It is also susceptible to canker and dieback and can suffer from damage caused by deer. Transplanting of mature trees should not be attempted, as the tree may have a difficult time surviving.
