Cultivars
The cultivars are separated into 2 different groups, Purple leaf types and Green yellow variegated leaf types.  All of the Purple leaf types are variations of atropurpurpa. Generally the following plants are frost tolerant and have a medium water requirement once established.

PURPLE LEAF TYPES
