How to Grow Purple Verbena Plant Indoors

Updated: July 24, 2023

Introduction

Purple verbena plants, also known as Verbena bonariensis, are beautiful flowering plants that can add a touch of color and elegance to any indoor space. These plants are native to South America and are characterized by their tall, slender stems and clusters of vibrant purple flowers. Growing purple verbena plants indoors can be a rewarding experience, as they not only provide visual appeal but also attract pollinators such as butterflies and bees. In this article, we will discuss the step-by-step process of growing purple verbena plants indoors.

Step 1: Choosing the Right Container

When growing purple verbena plants indoors, it is important to select the right container for planting. Choose a container that is at least 6-8 inches deep and has drainage holes at the bottom to prevent waterlogging. The container should also be wide enough to accommodate the spread of the plant’s roots.

Step 2: Selecting the Right Soil

Purple verbena plants prefer well-draining soil that is rich in organic matter. You can create a suitable potting mix by combining equal parts of garden soil, peat moss, and perlite or vermiculite. This mixture will provide the necessary nutrients and moisture retention while allowing excess water to drain away.

Step 3: Planting the Purple Verbena Seeds

To start growing purple verbena plants indoors, you can either sow seeds directly or transplant seedlings. If you choose to sow seeds, fill the container with the potting mix and sprinkle the seeds evenly on top. Gently press the seeds into the soil, but do not cover them completely as they require light for germination. Mist the soil with water to keep it moist but avoid overwatering.

Step 4: Transplanting Seedlings (Optional)

If you prefer to start with seedlings, you can purchase them from a local nursery or grow them from seeds in a separate tray. Once the seedlings have developed a few true leaves, carefully transplant them into the prepared container. Make sure to handle the seedlings gently to avoid damaging their delicate roots.

Step 5: Providing Adequate Light

Purple verbena plants thrive in bright, indirect sunlight. Place the container near a south-facing window or provide artificial grow lights to ensure they receive at least 6-8 hours of light per day. Avoid placing the plants in direct sunlight as it can scorch the leaves.

Step 6: Watering and Fertilizing

Purple verbena plants require regular watering to keep the soil evenly moist. Water the plants whenever the top inch of soil feels dry to the touch. Avoid overwatering as it can lead to root rot. During the growing season, you can feed the plants with a balanced liquid fertilizer diluted to half strength every two weeks. This will provide them with the necessary nutrients for healthy growth and blooming.

Step 7: Pruning and Deadheading

To promote bushier growth and prolong flowering, it is important to prune purple verbena plants regularly. Pinch back the tips of the stems when they are about 6-8 inches long to encourage branching. Remove any dead or faded flowers by cutting them off at the base, a process known as deadheading. This will prevent the plant from expending energy on seed production and redirect it towards new growth and blooming.

Step 8: Dealing with Pests and Diseases

While purple verbena plants are generally resistant to pests and diseases, they can occasionally be affected by aphids or powdery mildew. To deal with aphids, you can spray the plants with a solution of water and mild dish soap or rub them off gently with a cotton swab dipped in rubbing alcohol. Powdery mildew can be prevented by ensuring good air circulation around the plants and avoiding overhead watering.

Step 9: Transplanting and Repotting

As purple verbena plants grow, they may outgrow their initial container. When this happens, it is important to transplant them into a larger pot to provide more space for their roots to spread. Choose a container that is one size larger than the current one and follow the same planting process as mentioned earlier. Repotting should be done in spring or early summer when the plants are actively growing.

Conclusion

Growing purple verbena plants indoors can be a delightful experience, allowing you to enjoy their vibrant purple flowers and attract pollinators to your living space. By following these step-by-step instructions, you can successfully cultivate these beautiful plants and add a touch of elegance to your indoor garden. Remember to provide them with the right container, soil, light, water, and nutrients, and regularly prune and deadhead for optimal growth and blooming. With proper care, your purple verbena plants will thrive indoors and bring joy to your home all year round.
