What are Coralberries?
Coralberry shrub (Symphoricarpos orbiculatus) is a member of the Caprifoliaceae family and is native to such areas of Texas, eastward to Florida and New England and north again through Colorado and South Dakota. In its indigenous regions, coralberry shrub is considered to be more a weed than a garden specimen.
Growing coralberry plants thrive in clay and loam soils found in the understory or shaded areas of the woods. Coralberry shrubs have a spreading habitat, which may be useful as an erosion control method.
This shrubby ground cover has slender barked stems with greenish-blue foliage that turns red in the autumn. Coralberry shrubs bear purplish pink berries at this time as well, and provide a lovely pop of color during winter months, although not a food source. Indian currant berries contain a toxin called saponin, which is also found in Digitalis (foxglove), and may be harmful to small animals or even humans. The dense thicket of growing coralberry plants, however, provides nesting sites for many rodents, small mammals and songbirds and its flowers are frequented by butterflies and moths.
The mild toxin of coralberry shrubs also has mild sedation properties and, as such, the berries have been harvested by Native Americans and used as a treatment for eye pain. The dried roots, called devil’s shoestrings, have been used by indigenous peoples as a method for stunning the fish and making them easier to catch.
