Once you’ve grown Persian shield, also called strobilanthes, you’ll want to plant it every spring. That’s because this amazing plant develops spectacular, iridescent purple, green, and black foliage that shines in sun or partial shade. The plants grow 18-36 inches tall so they make an ideal centerpiece in a large pot or planter. Persian shield is heat- and drought-tolerant and is resistant to both deer and rabbits. These easy-care plants look great right up until first frost.
