Unveiling the Distinctions: Catmint vs. Creeping Charlie
At first glance, catmint (Nepeta) and creeping charlie (Glechoma hederacea) can appear quite similar, both sporting heart-shaped leaves and a tendency to form dense mats. However, a closer inspection reveals subtle yet significant differences that set these two apart:
1. Leaf Shape and Texture:
- Catmint: Catmint leaves are typically more elongated and pointed, with a slightly rough texture.
- Creeping Charlie: Creeping Charlie leaves are more rounded and have a smoother, almost velvety texture.
2. Leaf Arrangement:
- Catmint: Catmint leaves grow in pairs opposite each other on the stem.
- Creeping Charlie: Creeping Charlie leaves have a more scattered arrangement, with some growing directly from the stem and others emerging from the leaf axils.
3. Flower Appearance:
- Catmint: Catmint boasts beautiful, fragrant flowers that bloom in clusters at the top of the stems. The flowers are typically blue, purple, or white, depending on the variety.

4. Growth Habit:
- Catmint: Catmint is generally an upright plant, reaching heights of 1 to 3 feet depending on the variety. It forms a bushy, clumping habit.
- Creeping Charlie: Creeping Charlie is a low-growing, spreading plant that tends to form dense mats. It can aggressively spread through underground runners, making it a notorious groundcover.
5. Fragrance:
- Catmint: Catmint is known for its strong, aromatic scent, reminiscent of mint. This fragrance attracts pollinators and repels pests.
- Creeping Charlie: Creeping Charlie has a milder, less noticeable scent compared to catmint.

The Challenges of Creeping Charlie: A Garden Menace
While creeping charlie may initially appear charming with its lush foliage, its invasive nature quickly turns it into a garden nightmare. Its aggressive spreading can quickly overwhelm other plants, turning a well-maintained garden into a tangled mess.

Managing Creeping Charlie: Strategies for Control
If you find yourself battling creeping charlie in your garden, here are some strategies to help you regain control:
- Hand-Pulling: Regularly remove creeping charlie plants by hand, making sure to dig up the roots and runners.
- Mulching: Applying a thick layer of mulch around desirable plants can help suppress the growth of creeping charlie.
- Herbicides: In severe cases, you can use herbicides specifically designed for creeping charlie, but always follow label instructions carefully.
- Prevention: Be vigilant about preventing the spread of creeping charlie by regularly inspecting your garden and removing any new seedlings.
Choosing the Right Plant: Catmint or Creeping Charlie?
When deciding between catmint and creeping charlie, it’s crucial to consider your gardening goals and preferences. If you’re seeking a beautiful, fragrant plant that attracts pollinators and adds a touch of charm to your garden, catmint is an excellent choice. However, if you’re looking for a groundcover, be cautious about creeping charlie’s invasive nature. It’s best to choose a non-invasive alternative like thyme or clover.
Beyond the Garden: The Fascinating World of Catnip
While catmint and creeping charlie are often mistaken for each other, it’s important to note that catnip (Nepeta cataria) is a distinct species within the Nepeta genus. Catnip is famous for its psychoactive effects on cats, causing them to exhibit playful and euphoric behaviors. This unique property is attributed to the presence of a compound called nepetalactone.
The Final Bloom: A Garden Odyssey
Understanding the differences between catmint and creeping charlie is crucial for creating a thriving and well-maintained garden. While catmint offers beauty, fragrance, and beneficial properties, creeping charlie can quickly become a nuisance. By choosing the right plant for your needs and employing effective control measures, you can ensure a garden that flourishes with both beauty and harmony.
