Persian shield: an exotic plant species


Persian shield (Strobilanthes dyerianus) is a stunning ornamental plant that comes from the warm and humid nation of Myanmar and grows there as an evergreen perennial.

It belongs to the Acanthaceae family, which mainly consists of flowering tropical plants.

With its unique iridescent purple leaves, S. dyerianus has had no difficulty in attracting the attention of US gardeners and is now grown here as an annual, perennial and houseplant.

Exotic and intense

This striking tropical species, sometimes called Bermuda conehead, thrives on heat and moisture and delivers its most brilliant color in partially shaded locations.

Its leaves shimmer positively in neon violet tones, veined green. With too much light, the colors are less impressive.

The leaves of S. dyerianus are about six inches long and stems can reach three feet. In regions where the plant thrives all year round, small, tubular, conical blue flowers bloom in autumn or winter. They remind me a little of Virginia Bluebells and accompany the shiny tropical foliage in an unusual way.

In cooler regions where there is grows as a summer yearbookThe Persian shield usually succumbs to frost before flowering.

If you live in a cool climate zone, bring Persian shield plants into the house for the winter:

Use a high quality potting soil and a container with sufficient drainage holes for indoor growing. Keep the soil moderately moist by watering it weekly. Fertilize quarterly with a slow-acting fertilizer according to the package instructions.

I multiply new plants by cutting young stems about two inches in length, placing them in a cup of water until roots form, and then planting them in soil.

Where to buy

plant S. dyerianus outside in the garden or cultivate indoors as houseplants.
