Episcia 'Ember Lace' [one of the variegated Episcia, sometimes called pink leaved. Gets confusing since some non-variegated Episcia can also have pink leaves but are not as sensitive to their environment as the variegated types.]
The color of Trifolium 'Dark Dancer' is somewhere between chocolate and dark purple. This variety of white clover is a good edging plant or ground cover and is hardy in zones 4-10. A Dark Dancer Trifolium plant in a 4.5-inch pot is $7.95 from Easy to Grow Bulbs.
