Why Gardeners Adore Lavender and Catmint
When it comes to creating a vibrant, appealing garden that practically cares for itself, few plant pairings rival the effectiveness and beauty of lavender and catmint.
They offer a blend of aesthetic appeal, ecological benefits, and straightforward cultivation that makes them a top choice for many gardeners.
The Allure of Lavender (Lavandula)
Lavender, with its iconic purple spikes and unmistakable fragrance, is a true garden classic. It evokes images of sun-drenched Mediterranean fields and peaceful cottage gardens.
Beyond its beauty, lavender brings a host of benefits:
- Aromatic Delight: Its essential oils are prized for their calming scent, perfect for sachets, culinary uses, and simply enjoying in the garden.
- Pollinator Magnet: Bees, butterflies, and other beneficial insects flock to its nectar-rich flowers, boosting your garden’s ecosystem.
- Drought Tolerance: Once established, most lavender varieties are incredibly water-wise, making them ideal for xeriscaping and dry climates.
- Deer and Rabbit Resistance: The strong scent and flavor generally deter these common garden pests, protecting your blooms.
Popular varieties range from the hardy English lavenders (Lavandula angustifolia) like ‘Munstead’ and ‘Hidcote’ to the more tender French (Lavandula stoechas) and Lavandin types (Lavandula intermedia) such as ‘Grosso’.
The Charms of Catmint (Nepeta)
Often mistaken for lavender due to its similar purple flowers and mounding habit, catmint is a powerhouse in its own right. It’s a plant of incredible resilience and generosity.
Catmint offers distinct advantages:
- Extended Bloom Time: Many catmint varieties bloom from late spring all the way through fall, providing continuous color when other plants fade.
- Incredibly Tough: It tolerates a wide range of soils, heat, and even some shade, making it adaptable to many garden conditions.
- Low Maintenance: It rarely needs fertilizing and shrugs off most pests and diseases.
- Pollinator Haven: Like lavender, catmint is a fantastic food source for bees and other beneficial insects, supporting local biodiversity.
Varieties like ‘Walker’s Low’ and ‘Six Hills Giant’ are particularly popular for their robust growth and abundant flowering. These Nepeta x faassenii cultivars are often sterile, meaning they won’t reseed aggressively.
Choosing the Right Varieties for Your Garden
Selecting the perfect lavender and catmint varieties is crucial for ensuring they thrive in your specific garden environment.
Consider your climate, soil conditions, and desired plant size and bloom characteristics.
Selecting Lavender Cultivars
Your local USDA hardiness zone will heavily influence which lavender types will perform best. English lavenders are generally the most cold-hardy, while French and Spanish lavenders prefer warmer climates.
Think about the mature size you need. Some lavenders grow into substantial shrubs, while others remain compact. Always check the plant tag for expected height and spread.
- English Lavender (Lavandula angustifolia): Best for colder zones (USDA 5-9). Known for its sweet fragrance and culinary uses. Varieties like ‘Hidcote’ and ‘Munstead’ are compact and reliable.
- Lavandin (Lavandula intermedia): A hybrid of English and spike lavender. Taller, more vigorous, and often used for essential oil production. ‘Grosso’ and ‘Provence’ are popular, tolerating zones 5-9.
- Spanish Lavender (Lavandula stoechas): Distinctive “bunny ear” bracts. Prefers warmer zones (7-10) and can be less fragrant than English types, but visually striking. ‘Anouk’ and ‘Otto Quast’ are good choices.
Picking Your Perfect Catmint
Catmint varieties offer a spectrum of sizes and bloom intensities. Consider where you want to plant it and how much space it can fill.
Some catmints are excellent groundcovers, while others form substantial mounds.
- ‘Walker’s Low’ (Nepeta x faassenii): A popular, award-winning cultivar known for its long bloom time and tidy, mounding habit (around 2-3 feet tall and wide). Despite its name, it’s not particularly low-growing.
- ‘Six Hills Giant’ (Nepeta x faassenii): True to its name, this one gets larger, reaching 3-4 feet tall and wide. It’s excellent for larger borders or as a substantial filler.
- ‘Cat’s Meow’ (Nepeta faassenii): A more compact selection than ‘Walker’s Low’, staying around 1-1.5 feet tall, making it ideal for smaller spaces or front-of-border planting.
- ‘Junior Walker’ (Nepeta x faassenii): A dwarf version of ‘Walker’s Low’, perfect for containers or tight spots, usually under a foot tall.
Getting Started: Planting Lavender and Catmint for Success
Proper planting is the foundation for healthy, long-lived lavender and catmint plants. Don’t worry—these flowers are perfect for beginners!
A little attention to site selection and soil preparation will pay dividends in vibrant blooms and robust growth.
Site Selection and Soil Preparation
Both lavender and catmint are sun-worshippers. They absolutely thrive in full sun, meaning at least 6-8 hours of direct sunlight per day. Less sun often leads to leggy growth and fewer flowers.
The most critical factor for these plants is excellent drainage. They hate wet feet, which can quickly lead to root rot. If you have heavy clay soil, you’ll need to amend it significantly.
- Improve Drainage: Mix in plenty of organic matter like compost, grit, or small gravel to break up clay. Consider planting in raised beds or on a slight mound if drainage is a persistent issue.
- Soil pH: Lavender prefers slightly alkaline soil (pH 6.5-7.5), while catmint is more adaptable but also prefers neutral to slightly alkaline conditions. A simple soil test kit can help you determine your current pH.
Planting Techniques
The best time to plant is in spring after the last frost, or in early fall in warmer climates. This gives the plants time to establish their root systems before extreme temperatures hit.
When you’re ready to plant, follow these steps:
- Dig the Hole: Dig a hole twice as wide as the plant’s root ball and just as deep.
- Loosen Roots: Gently tease apart any circling roots on your nursery plant.
- Plant at Proper Depth: Place the plant in the hole so the top of the root ball is level with the surrounding soil. Avoid burying the crown.
- Backfill and Water: Backfill with your amended soil, gently firming it around the base. Water thoroughly to settle the soil and eliminate air pockets.
- Space Appropriately: Ensure you leave enough space between plants for their mature size. Good air circulation is vital to prevent fungal diseases.
Essential Care for Thriving Lavender and Catmint
Once established, both lavender and catmint are remarkably low-maintenance. However, a little thoughtful care will ensure they reach their full potential, gracing your garden with beauty for years to come.
Watering Wisdom
The biggest mistake gardeners make with lavender and catmint is overwatering. These plants are built for dry conditions.
- Establishment Phase: For the first growing season, water regularly (once or twice a week, depending on heat and soil) to help them establish deep root systems. Feel the soil; it should be dry a few inches down before watering again.
- Mature Plants: Once established, they are highly drought-tolerant. You’ll only need to water during prolonged dry spells or extreme heat. Err on the side of underwatering rather than overwatering.
Always ensure water drains freely and never let them sit in soggy soil. Standing water is a death sentence for these plants.
Pruning for Peak Performance
Pruning is the most important care task for both lavender and catmint, encouraging bushier growth, more blooms, and preventing them from becoming woody and sparse.
Always use sharp, clean bypass pruners for precise cuts that heal quickly.
-
Lavender Pruning:
- First Year: Lightly prune after the first flush of flowers to encourage branching.
- Annual Pruning (Early Spring): Cut back about one-third of the plant’s height, shaping it into a compact mound. Avoid cutting into old, woody stems that have no green leaves, as they may not regrow.
- Deadheading: Snip off spent flower stalks throughout the season to encourage more blooms and keep the plant tidy.
-
Catmint Pruning:
- Shearing After First Bloom: Once the first flush of flowers fades, shear the plant back by about one-third to one-half. This rejuvenates the plant and encourages a robust second (and often third) flush of blooms.
- Tidying Up (Late Fall/Early Spring): If desired, you can cut it back hard in late fall or early spring to remove old foliage and promote fresh growth.
Fertilization (or Lack Thereof)
Here’s some good news: both lavender and catmint are not heavy feeders. In fact, too much fertilizer, especially high-nitrogen formulas, can lead to lush foliage but fewer flowers, and can even shorten their lifespan.
If your soil is extremely poor, a light application of a balanced, slow-release granular fertilizer in early spring might be beneficial, but for most gardens, no additional feeding is necessary.
Pest and Disease Management
One of the many joys of growing these plants is their natural resistance to most pests and diseases. Their aromatic oils act as natural deterrents.
- Common Issues: The primary problems stem from poor drainage and overwatering, which can lead to fungal issues like root rot or powdery mildew. Ensure good air circulation and proper watering to prevent these.
- Pro Tip: If you notice any signs of disease, such as yellowing leaves or wilting, first check your watering habits and soil drainage. Often, adjusting these conditions is all that’s needed. For persistent or severe pest issues, consult a local nursery expert for targeted, organic solutions.
Design Inspiration with Lavender and Catmint
The combination of these two plants offers incredible versatility in garden design. Their similar color palette but distinct textures create dynamic visual interest.
Companion Planting
Both lavender and catmint are excellent companion plants, enhancing the beauty and health of their neighbors.
- Roses: Their purple hues beautifully complement roses, and their strong scents can help deter aphids.
- Coneflowers (Echinacea), Sedum, and Ornamental Grasses: These pairings create a naturalistic, drought-tolerant border with varying textures and heights.
- Alliums: The spherical blooms of ornamental onions provide a striking contrast to the spiky flowers.
They also attract beneficial insects like ladybugs and lacewings, which prey on common garden pests, naturally protecting your other plants.
Creating a Sensory Garden
Beyond their visual appeal, lavender and catmint are stars in a sensory garden. Plant them along pathways, near seating areas, or by entryways where their fragrance can be easily enjoyed when brushed against.
Mass plantings create a stunning sea of purple and blue, drawing the eye and providing a strong focal point. Use them as border plants, in drifts, or as informal hedges.
Practical Uses and Harvest
The benefits of these plants extend beyond the garden bed:
- Lavender: Harvest flower stalks just as the lowest flowers begin to open. Hang them upside down in a cool, dark, well-ventilated area to dry. Use dried lavender for sachets, potpourri, culinary creations (ensure it’s culinary-grade English lavender), or homemade essential oils.
- Catmint: While less commonly used for human consumption, its leaves can be steeped for a mild, calming tea. Of course, many cat owners love to share sprigs with their feline friends, who often react with playful delight. Use caution and introduce small amounts to ensure your cat reacts positively.
Troubleshooting Common Issues with Lavender and Catmint
Even the toughest plants can sometimes encounter a hiccup. Here’s how to address some common challenges you might face with your lavender and catmint.
Why Isn’t My Lavender Blooming?
If your lavender is looking green but not producing its characteristic purple spikes, several factors could be at play:
- Insufficient Sunlight: Lavender needs at least 6-8 hours of direct sun. Less light means fewer flowers.
- Improper Pruning: Not pruning at all can lead to woody plants with diminished blooms. Cutting too hard into old wood can also prevent flowering.
- Too Much Nitrogen: High-nitrogen fertilizers promote leafy growth at the expense of flowers.
- Young Plant: Sometimes, new plants need a season or two to establish before blooming profusely.
Adjusting its sun exposure or pruning routine often solves the problem.
My Catmint Looks Leggy – What to Do?
Leggy, sprawling catmint is a common sight, but it’s easily remedied:
- Shear It Back: After the first flush of flowers, give it a good trim, cutting back by about one-third to one-half. This encourages new, compact growth and a fresh wave of blooms.
- Check Sunlight: Like lavender, catmint can get leggy if it’s not receiving enough sun, as it stretches to find more light.
Regular shearing is key to maintaining a full, attractive catmint plant throughout the season.
Dealing with Overwatering or Poor Drainage
The most frequent cause of distress for both these plants is too much moisture. Symptoms include:
- Yellowing Leaves: Especially on lower foliage.
- Wilting: Paradoxically, plants can wilt from overwatering because their roots are suffocating.
- Root Rot: The most severe symptom, leading to plant death.
If you suspect overwatering, immediately stop watering. If the plant is in heavy clay, you might need to carefully dig it up, amend the soil with more grit and compost, and replant it on a slight mound. For plants in containers, ensure drainage holes are clear.
Frequently Asked Questions About Lavender and Catmint
How often should I water newly planted lavender and catmint?
For the first growing season, water once or twice a week, allowing the top few inches of soil to dry out between waterings. This encourages deep root development. After establishment, they are very drought-tolerant and rarely need supplemental water except during prolonged dry spells.
Can I grow these plants in containers?
Absolutely! Both lavender and catmint thrive in containers, provided they have excellent drainage. Choose a pot with drainage holes and use a well-draining potting mix. Container plants will need more frequent watering than those in the ground, especially during hot, dry weather.
Are lavender and catmint safe for pets?
Lavender is generally considered non-toxic to cats and dogs, though large ingestions can cause mild stomach upset. Catmint (Nepeta) is well-known for its stimulating effect on cats (like catnip), but it’s also non-toxic. Always monitor your pets around new plants.
What’s the main difference between them visually?
While both have purple flowers and gray-green foliage, lavender typically has more rigid, upright flower spikes and linear, often silvery leaves. Catmint usually has more delicate, airy flower spikes and softer, slightly more rounded leaves, giving it a somewhat “fluffier” appearance. Catmint also tends to bloom for a much longer period.
When is the best time to plant them?
The ideal time to plant both lavender and catmint is in the spring after the last frost, giving them the entire growing season to establish strong root systems. In warmer climates with mild winters, early fall planting is also a good option.
Conclusion
Embracing the beauty and resilience of lavender and catmint is one of the most rewarding decisions you can make for your garden. Their combined strengths—fragrance, vibrant color, pollinator appeal, and incredible hardiness—make them an unbeatable duo.
