Strobilanthes dyeriana, the Persian shield or royal purple plant,[1] is a species of flowering plant in the acanthus family Acanthaceae, native to Myanmar (formerly Burma).


The Latin specific epithet dyeriana honours the English botanist Sir William Turner Thiselton-Dyer (1843-1928).[2]


Growing to 1 m (3.3 ft) tall and broad, it is a tropical evergreen shrub, cultivated for its dark green foliage with bright, metallic-purple stripes radiating outward from the central leaf vein. In proper conditions, it will also produce pale purple flowers.


With a minimum temperature of 10 °C (50 °F), S. dyeriana grows best in USDA Zones 10–11.[3] In more temperate climates it is grown as a houseplant. It prefers a warm, humid position in good light. As the intense purple colour may fade with age, it is often treated as an annual.[3] In the UK it has gained the Royal Horticultural Society's Award of Garden Merit.[1][4]
