Persian Shield (Strobilanthes dyerianus) is a tropical perennial plant that is native to Myanmar (Burma). It is known for its vibrant, iridescent purple-blue leaves that have a metallic sheen, and its small, violet-blue flowers that bloom in the summer.

It is commonly grown as an ornamental plant and can be used in a variety of garden settings such as mixed borders, woodland gardens, and as a houseplant. Persian Shield plants are relatively easy to grow and care for, but they do require warm temperatures and high humidity to thrive. They prefer well-draining, slightly acidic soil and need consistent moisture.

They are also sensitive to frost and will not survive in temperatures below 50 F, so they should be protected from cold weather. Persian Shield is also susceptible to pests and diseases, such as spider mites, powdery mildew, and leaf spot, but these can be controlled with proper care and attention.

How to Grow Persian Shield from Seed?

Growing Persian Shield from seed can be a bit challenging, but it is possible with proper care and conditions. Here are some tips on how to grow Persian Shield from seed:

  1. Collect fresh seeds: Collect the seeds from Persian Shield plants in the fall, when they are ripe and ready to harvest.
  2. Plant the seeds: Plant the seeds in seed trays or pots filled with seed compost or a mixture of peat moss and sand. Cover the seeds with a thin layer of soil and keep the soil consistently moist but not waterlogged.
  3. Provide proper temperature and light: Persian Shield seeds require warm temperatures to germinate, so place the seed tray or pots in a warm, bright location. Provide indirect light, as too much direct sunlight can dry out the soil and prevent germination.
  4. Transplant the seedlings: Once the seedlings have emerged, transplant them into individual pots. When the seedlings are large enough, transplant them into their permanent location in the garden.
  5. Provide the right conditions: Persian Shield plants require warm temperatures and high humidity to thrive. They also need well-draining, slightly acidic soil and consistent moisture.
  6. Be patient: Growing Persian Shield from seed can be a slow process, so be patient and don’t rush the process.

Persian Shield is a relatively easy to grow and care for plant, but it does require certain conditions to thrive. Here are some tips on how to care for Persian Shield:

  1. Plant in the right location: Persian Shield prefers bright, indirect light and warm temperatures (above 60°F) to thrive. It’s not frost-hardy and should be protected from cold temperatures.
  2. Watering: Water Persian Shield regularly to keep the soil consistently moist, but not waterlogged. They prefer high humidity and will benefit from regular misting or placing a tray of water near the plant.
  3. Fertilizing: Fertilize Persian Shield once a month with a balanced, water-soluble fertilizer during the growing season.
  4. Pest and Disease Control: Keep an eye out for pests such as spider mites and diseases such as powdery mildew. These can be controlled with proper care and attention.
  5. Pruning: Prune Persian Shield to control its size and shape, and to encourage bushier growth.
  6. Potting and Repotting: Repot Persian Shield every 2-3 years in a container one size larger, with well-drained, slightly acidic potting soil.
  7. Overwintering: Persian Shield is not frost hardy, so it should be overwintered indoors in a bright, cool room (above 50°F) with high humidity.
  8. Keep an eye on the humidity: Persian Shield prefers high humidity, so consider using a humidifier or placing a tray of water near the plant to increase humidity.

It’s important to note that, Persian Shield is a tropical plant and it may not survive in areas with extended freezing temperatures.

How to Propagate Persian Shield

Persian Shield can be propagated through several methods including:

  1. Stem cuttings: Take stem cuttings in the spring or summer, making sure each cutting has at least one leaf node. Dip the cuttings in rooting hormone powder and plant them in a well-draining potting mix. Keep the cuttings in a warm and humid location, and keep the soil consistently moist. Rooting should occur in about 2-3 weeks.
  2. Division: Persian Shield can be divided during the spring or fall, when it is dormant. Carefully dig up the plant, and divide the root ball into several sections, each with at least one shoot and root. Replant the divisions in well-draining soil.
  3. Air layering: Air layering is a method of propagating woody plants by encouraging roots to form on a stem while it is still attached to the parent plant. This method can be done during the growing season, by making a small incision in the stem, dusting it with rooting hormone powder, and covering it with a plastic wrap. Roots should form in about a month.

Keep in mind that the process of propagation will take some time, and it’s important to be patient and to provide the right conditions for the cuttings, divisions, or layers to root.

How to Protect Persian Shield from Overwintering?

Persian Shield is not frost-hardy and should be protected from cold temperatures during the winter. Here are some tips on how to protect Persian Shield from overwintering:
