Small, pointed leaves on arching stems begin gold-yellow, turning chartreuse with age and more shade. Experiment to find the exposure that keeps foliage the color you want. Stems and leaf veins become increasingly magenta-red. From early summer through fall, 2" red-magenta and purple flowers dangle along the stems. Plant it where it can cascade.
Bright colors for low-light areas. Can be over-wintered indoors, where they bloom well.
