How to Make Obedient Plant Behave in Your Flower Garden

4 Min Read

The obedient plant, scientifically known as Physostegia virginiana, might sound obedient in name, but it can be quite the unruly presence in your garden if left unchecked.

Known for its tendency to spread rapidly and invade neighboring plants, this perennial can quickly become a headache for gardeners.

However, with the right strategies and techniques, you can make the obedient plant behave and even turn it into a delightful addition to your flower garden. Here are some tips to help you tame this wild beauty:

Choose the Right Location

Obedient plants thrive in full sun to partial shade and moist, well-drained soil. However, they have a reputation for spreading aggressively, so it’s crucial to select their planting location wisely.

Opt for areas with boundaries, such as along fences or in contained garden beds, to prevent them from encroaching on other plants. Additionally, consider planting them in pots or using root barriers to control their spread further.

Regular Pruning and Deadheading

Like many vigorous growers, obedient plants benefit from regular pruning and deadheading to keep them in check.

Pruning not only helps maintain their shape and size but also prevents them from overpowering neighboring plants. Deadheading, or the removal of spent flowers, encourages continuous blooming and prevents self-seeding, which can lead to even more invasive growth.

Be sure to use sharp, clean pruners to avoid damaging the plant and remove any dead or diseased foliage as well.

Divide and Conquer

Obedient plants have a tendency to form dense clumps over time, which can contribute to their invasive behavior.

To prevent overcrowding and maintain their vigor, divide mature plants every few years in early spring or fall. Carefully dig up the clump, separate the individual rhizomes, and replant them in their desired locations.

This not only helps control their spread but also revitalizes the plants, promoting healthier growth and more abundant blooms.

Provide Adequate Support

Obedient plants have sturdy stems that can grow quite tall, especially when in full bloom.

To prevent them from flopping over and creating a messy appearance in your garden, provide adequate support early in the growing season. Install stakes or plant supports around the base of the plant and gently tie the stems to them as they grow.

This not only keeps the plants upright but also helps showcase their beautiful flower spikes without overshadowing other garden favorites.

Regular Maintenance and Vigilance

Finally, maintaining a vigilant eye and staying on top of regular maintenance tasks is essential for keeping obedient plants in line.

Regularly check for signs of invasive growth or spreading runners and take prompt action to remove any unwanted shoots or rhizomes. Stay proactive in managing their growth and be prepared to intervene as needed to prevent them from taking over your garden.

With consistent care and attention, you can ensure that obedient plants behave themselves and remain a charming addition to your flower garden.


While the obedient plant may have a knack for testing your gardening skills, with the right approach, you can tame its unruly nature and harness its beauty to enhance your flower garden.

By choosing the right location, practicing regular pruning and division, providing adequate support, and staying vigilant with maintenance, you can enjoy the presence of these lovely perennials without letting them run amok.

With a little patience and perseverance, you’ll master the art of making obedient plants behave and create a stunning garden oasis for years to come.
