Heuchera, better known as Coral Bells, is THE foliage perennial for your shade garden! 

This variety of perennials boast leaves of a brilliant purplish black like you have never before seen...deep purple foliage threaded with dark silvery veins is sure to spice up any location. 

New growth is of a wine color, and the undersides of all leaves are a plum purple.
 
The Amethyst Mist Coral Bells does produce small, cream colored flowers in spring, but these blooms cannot hold a candle to the magnificent, long lasting foliage for which this plant is known. 
 
Coral Bells are great container plants and look marvelous in a hanging basket. 

A vigorous grower, Amethyst Mist is an excellent ground cover, border plant or edger. 

For a winning combo try pairing with an ornamental grass like Carex Evergold or another foliage favorite, the Hosta.
