It is hardy in USDA hardiness zones 9 to 11, but in milder locations, it is most typically cultivated indoors or as a summer annual. Persian shield may die back to the ground after frost in zone 9, and during mild winters in zones 7 and 8, but it will survive and sprout the next season.
Can I grow Persian shield from seed?
Persian shield can be grown from seed, however seeds are unlikely to be found in an indoor environment. Instead, propagate by cutting the stem tips off during repotting. Place the cuttings in seed-starting soil and keep them warm and damp until new growth appears.
Where do you plant Persian shield?
In full sun to light shade, the plant thrives in a pot indoors or out. Provide an uniform amount of moisture and a high level of humidity. Placing a thin layer of rocks on a saucer and balancing the pot on top is the greatest technique to add more humidity to a Persian shield indoors. Fill the saucer with water. This keeps the roots out of the water while increasing the humidity in the air through evaporation.
In warm climates, Persian shield can be grown outside and planted in the ground as part of a border display. Treat the plant as an annual in cool zones or bring it inside at the end of the summer.

Size & Growth
Persian Shield can reach heights of 4 feet tall and 4 feet broad in a frost-free environment.
It is unlikely to grow taller or broader than 3 feet outside of USDA hardiness zones 10 and 11.
Flowering & Fragrance
It’s unusual for this plant to bloom outside of its natural habitat. The plant may bloom in the autumn or winter in particularly warm, humid environments.
Persian Shield is a seasonal bloomer that produces little, five-lobed violet flowers every now and then.
Individually, the flowers are relatively small. They do, however, grow in attractive cone-shaped bunches.
The plant’s popular name, Bermuda Conehead, comes from the shape of its inflorescences.
Foliage
Although the flowers are lovely and even showy, the silvery/iridescent purple foliage is the main attraction of this plant.
These foliage plants have purple leaves that are oval and lance-shaped. The base hue is a dark green with a silvery purple undertone.
The undersides of the leaves are a dark purple color. Leaves can grow up to 8 inches long.
Light & Temperature
The Persian Shield thrives in a wide range of light conditions, from partial shade to full sun.
If you live in a cooler climate, the plant may require full sun during the summer months to achieve its best color.
When overwintering, keep the plant in a bright, sunny area like a potted or container plant.
It’s a good idea to chop it back before the winter weather arrives in these zones, then cover it during the harshest months.
Take cuttings as a precaution in case your plant fails to regrow from the roots.
Watering & Feeding
This plant requires only modest watering, although it does require dependably moist soil.
It’s a good idea to develop a weekly watering routine when growing as a houseplant to keep the soil evenly moist.
Use a slow-release plant food to fertilize your plants multiple times a year (3). Carefully follow the instructions on the package.
Soil & Transplanting
It prefers constant dampness but cannot stand in water. It is critical to have well-drained soil.
Use a high-quality, organic-rich potting soil to keep Persian Shield as a houseplant. There should be lots of drainage holes in the container.
Grooming & Maintenance
Preparing Persian Shield for overwintering and keeping them safe throughout the winter can, however, is difficult.
They can be left to grow to their full height and width, or they can be pinched back to encourage compact, bushy growth.
What plants look good with Persian shield?
I have other tropicals in a raised bed, so the plant can grow into the earth and get plenty of water.
Ferns, Caladiums, Lamb’s Ears, Silver Plectranthus, and Impatients are all ideal companion plants.
Another fantastic idea is to plant them among red or purple flowers or foliage to complement the Persian Shield’s colors.
During the summer months, this plant can be planted in the garden, but don’t let it get too chilly.
How do you look after Strobilanthes?
Your Strobilanthes dyerianus is accustomed to rich soil with plenty of plant materials that holds water as a tropical plant. To do this, use a soil that is both rich and well-drained. If you want to keep it moist, add more compost, vermiculite, or peat moss.
Most people grow them in containers since they are excellent container plants. They can, however, be used as bedding plants if you provide a well-drained planting space for them.
Why is my Persian shield crispy?
Dry air causes brown, crunchy leaves. This inhabitant of the tropics prefers damp air to look its best. Take a look at these simple methods for increasing the humidity in the area. When the roots have filled the pot, repot in the spring probably every couple of years.
Can Persian shield take full sun?
Persian shield thrives in both the sun and the shade. It requires constant watering when planted in full sun, especially in warmer areas, to keep it from wilting. Spread a 3- to 4-inch-deep layer of mulch over the soil around the Persian shield plant to make it easier to grow. This helps to keep the soil cool and moist for a longer period of time. If you grow Persian shield in pots, you can do the same thing!
Use a general-purpose fertilizer to fertilize Persian shield in the spring. For information on how much and how often to fertilize, refer to the package instructions.
Persian shield can be pruned at any time. Pinching it back every now and again promotes the plant to grow fuller and bushier, especially in the shade.
In Zone 10, Persian shield can be used as a landscape shrub. Grow it as an annual in other places.
