The Story

Plant Bio

Strobilanthes auriculata is an upright, clumping evergreen subshrub native to the damp understories of Myanmar. The species is characterized by opposite, lanceolate leaves with distinctive ear-like auricles at the base that clasp the stem.

The variety dyeriana, commonly known as Persian shield, is distinguished by its highly ornamental foliage featuring a metallic, iridescent violet and silver sheen on the upper leaf surfaces. The undersides of the leaves present a contrasting solid purple-maroon color.

Uses & Benefits:

Ornamental UsesProvides striking, iridescent purple and silver foliage that contrasts sharply with green garden plants.
Practical UsesFunctions as a highly adaptable container plant that can be easily overwintered indoors.
Ecological BenefitsOffers occasional nectar to generalist pollinators and hummingbirds during its rare winter-to-spring flowering periods.

Planting

How to Grow

  1. Select a planting site that receives dappled sunlight or partial shade, avoiding direct afternoon sun which scorches the foliage.
  2. Prepare the soil by incorporating organic matter to create a rich, well-draining medium with a neutral to slightly acidic pH.
  3. Set the plant at the same depth as its nursery container and water thoroughly to settle the soil around the roots.
  4. Maintain consistent moisture by watering whenever the top inch of soil feels dry, ensuring the ground remains damp but never waterlogged.

Pro Tip

Pinch out the growing tips regularly during the spring and summer to prevent leggy growth and maintain a dense, bushy form. Avoid cutting back into old, completely leafless woody stems, as they lack active nodes and will fail to reshoot.

Care Guide

Do

  • Pinch back the growing tips regularly during spring and summer to encourage a bushy, compact habit.
  • Apply a balanced liquid fertilizer monthly during the active growing season to maintain vibrant foliage coloration.
  • Wear gloves when pruning to protect sensitive skin from potential irritation caused by the plant's sap.
  • Bring container-grown plants indoors before the first autumn frost to overwinter them in a bright, humid room.

Don't

  • Do not plant in full, direct sunlight, as intense rays will bleach the metallic colors and scorch the leaves.
  • Do not allow the soil to dry out completely, as the foliage wilts rapidly and may suffer permanent damage.
  • Do not cut back into old, completely bare woody stems during spring pruning, as they will not regenerate new growth.
  • Do not overwater or allow the plant to sit in standing water, which triggers root rot.
