Persian Shield (Strobilanthes dyerianus): Iridescent Purple Foliage That's Easy to Grow

Botanical Name: Strobilanthes dyerianus

Persian Shield is a stunning, low-maintenance houseplant. Lance-shaped leaves shimmer with deep purple, green, and silver—colors that lighten with age.

Light-blue flowers may appear in summer but pale beside the foliage. Pinch off flower spikes as they appear—they weaken the plant.

Fast-growing and soft-stemmed. Cut back in spring when leggy. Pinch stem tips in spring/summer for a fuller, bushier plant.

Pruning Tip: Cut at an angle just above a node (leaf/branch attachment point).

Brown crispy leaves = dry air. This tropical native wants humidity to look its best.

Repot in spring when roots fill the pot (every couple years).
