Coleus may be the go-to foliage plant for some gardeners, but Persian Shield is a stunning foliage plant that works equally well. The irridescent purple leaves shimmer with a hint of silver. Each leaf can reach 4 to 7 inches long and 3 inches wide. And as if the color wasn't enough, the leaves also feature bold green stripes along the veins. Bushy habit, very heat tolerant. Best in shade to part sun.
