How to Grow Persian Shield: A Vibrant Annual for Your Garden


If you’re looking for a vibrant annual to add some color to your garden, look no further than Persian shield. With their flashy shimmering iridescence and metallic silver sheen, the leaves resemble small armor shields ready for battle.

Although the name of this plant means “Persian,” it is native to Myanmar (formerly Burma), not Persia. It’s an evergreen shrub that grows in hot climates.

It is grown as an annual or herbaceous perennial in cooler climates, and it is popular as a houseplant because it blooms in the winter.

However, the vivid violet color fades over time as outdoor perennials and indoor potted plants are usually removed after a couple of years.

Tips for Keeping Your Plants Healthy

If you live in a hot climate, you can plant Persian shield as an evergreen shrub. However, if you live in a cooler climate, it is best to grow it as an annual or herbaceous perennial.

Here are some tips for keeping your plants healthy:

  • Plant Persian shield in well-draining soil.
  • Water regularly, but do not over-water.
  • Fertilize monthly with a balanced fertilizer.
  • Cut back the plant after it blooms to encourage new growth.

Lighting and Temperature

Persian shield grows best in partial sun to full sun. It prefers humid conditions and will tolerate some shade, but it will not bloom as profusely.

It is a tropical plant that is not tolerant of frost, so it should be planted after all danger of frost has passed.

Soil

Soil that is too rich will cause the plant to produce more foliage than flowers. Fertilize Persian shield monthly with a balanced fertilizer such as 20-20-20.

Pinch back the tips of the stems in late spring to encourage branching and prevent leggy growth.

Fertilizer

Fertilizer isn’t necessary, but if you want to give your Persian shield a little boost, use a balanced fertilizer once a month.

Water regularly to keep the soil moist, but not soggy. These plants are drought tolerant, so don’t worry if you forget to water them occasionally.

Pruning

Pruning will help to keep your plant tidy and prevent it from becoming too leggy. Cut back the stems by a few inches every couple of weeks or so.

You can also remove any dead leaves or flowers as they appear.

Watering

Strobilanthes does not like to dry out, so make sure to keep the soil moist but not soggy. You can allow the top layer of soil to dry out a bit between watering.

Size

Persian shield grows to be about two to three feet tall and wide.

Flowering

Persian shield (Strobilanthes dyerianus) adds a splash of color to gardens in U.S. Department of Agriculture plant hardiness zones 11 through 12.

The shrub also makes a beautiful houseplant that can be brought outdoors for the summer months and then back inside when temperatures start to cool in fall.

Common Pests and Plant Diseases

Persian shield is a beautiful and exotic-looking plant that is native to Madagascar. The plant has large, glossy leaves that are striped with shades of green, purple, and silver.

Persian shield is a popular ornamental plant, and it is often used as a houseplant or in containers on patios and decks. While the plant is generally resistant to disease and pests, there are a few things that can cause problems.

One of the most common issues is aphids, which can be controlled with the use of horticultural oils. Whiteflies can also be problematic, especially when plants are stressed by drought.

Generally, however, Persian shield is a low-maintenance plant that will provide years of beauty with minimal care.

Propagating Persian Shield

Plants can be easily established by cutting stems in the manner used by the majority of delicate perennials.

Harvesting cuttings is best done in the spring and early summer, but it can also be done in the fall to start new plants in time for spring.

Here’s how it’s done:

Use sharp pruning tools to make the cuts. Cut about 3 inches of stem from a diseased plant, cutting just below the node.

The leaves must be removed from the bottom cut. Place the cutting in a nondescript container filled with peat.

To keep humidity in, moisten the potting medium and then place the container inside an unsecure plastic bag. Place it in a sunny location, but keep it out of direct sunlight.

Every day, remove the plastic bag for about 30 minutes to allow the plant to breathe. Spray it with a mister again before reattaching the plastic bag.

In about two weeks, roots will have formed and can then be transplanted into soil. With this method, you can easily start new plants from cuttings.

Types of Persian Shield

While there are no Persian shield cultivars to choose from, the Strobilanthes genus is massive, with over 350 species.

Additionally, other species that are commonly used in garden landscaping but are difficult to find in the garden plant market include Strobilanthes alternata, also known as Hemigraphis Alternate, and S. maculates, a Himalayan species.

Alternata is commonly referred to as “the waffle” plant and is frequently used as a groundcover or houseplant.

It is only hardy in zones 10-11 and there are numerous cultivars to consider, including ‘Belgian waffle,’ ‘Red Flaming Ivy,’ and Snow White. Maculates, on the other hand, is a Himalayan species with silver-flecked leaves. Lastly, S.

lactates is a Brazilian species with blotched white leaves. Consequently, while it may be difficult to find a Persian shield for your garden, there are plenty of other options available in terms of both cultivars and species.

Does Persian shield need sun or shade?

Persian shield (Strobilanthes dyerianus) is a beautiful tropical plant that is native to Myanmar. It is often grown as a houseplant or annual in temperate climates, and it is prized for its vibrant purple leaves.

Persian shield does best in partial shade, but it can also tolerate full sun. If it is grown in full sun, especially in hot weather, it will require regular watering to prevent it from dying.

Why is my Persian shield losing color?

Persian shield is a beautiful ornamental plant that is often grown for its colorful leaves. However, it is not uncommon for the leaves of this plant to lose their color over time.

This is most often seen on older leaves that are nearing the end of their life cycle. While there is nothing that can be done to prevent this from happening, exposure to brighter light may help to keep the leaves looking more vibrant for longer.

In general, however, the loss of color in Persian shield leaves is perfectly normal and should not be cause for concern.

Should I mist my Persian shield?

If you have a Persian Shield plant, it is important to provide high humidity in order for the plant to thrive. The leaves of the plant will dry out and drop off if the humidity is low.

You can raise the humidity around the plant by misting the foliage with water, but be sure to use rain water or distilled water so that you don’t damage the leaves.

When misting, avoid using water that contains chemicals like chlorine, as this can leave scratches on the leaves of the plant.

By providing high humidity and protecting the leaves of the plant, you can ensure that your Persian Shield will thrive.
