Persian Shield
Strobilanthes dyerianus
Family Acanthaceae

Persian shield looks airbrushed: purple and silver laid over green in a metallic sheen no photograph quite captures, on leaves that seem lit from inside. It may be the most jaw-dropping foliage plant most gardeners have never grown — the one visitors always stop at and ask about first.
It keeps its color best out of harsh sun, which makes it a natural for shade containers outdoors and bright rooms indoors, where it carries on as a 2-to-3-foot houseplant. The iridescence flatters everything planted near it, chartreuse especially. No pet-safety listing exists yet, so keep it out of chewing range — and in plain view.
