Quick Answers to Common Questions

How tall does Walker’s Low Nepeta Catmint Plant grow?

It typically reaches eighteen to twenty-four inches tall and spreads twenty-four to thirty inches wide at maturity.

When should I cut back my catmint for a second bloom?

Perform the Chelsea Chop in late May or early June when the first flush of flowers begins to fade, cutting the plant back by half.

Is Walker’s Low Nepeta Catmint Plant invasive?

No, it is a sterile hybrid that does not produce viable seed, so it will not spread aggressively or become weedy in your garden.

Can I grow this catmint in containers?

Yes, it thrives in containers with well-draining potting mix. Use a pot at least twelve inches wide and water more frequently than in-ground plants.

Why is my catmint flopping open in the middle?

Flopping usually indicates too much shade, overwatering, rich soil, or lack of the Chelsea Chop. Ensure full sun, lean soil, and prune in early summer.

What Makes Walker’s Low Special

The Story Behind the Name

Despite what the name might suggest, Walker’s Low Nepeta Catmint Plant is not particularly low growing. The name actually honors the garden where it was discovered. In the 1970s, a gardener named Mrs. Walker found this natural hybrid growing in her garden in Ireland. She shared it with the famous plantsman Jim Russell at Sunningdale Nurseries. He recognized its superior qualities and introduced it to the horticultural world. The “Low” part of the name refers to the Walker family garden, not the plant’s height. This variety grows to a respectable eighteen to twenty-four inches tall and can spread thirty inches wide or more.

Award Winning Pedigree

This catmint earned the prestigious Perennial Plant of the Year award in 2007 from the Perennial Plant Association. That honor goes to plants that are suitable for a wide range of climates, low maintenance, pest and disease resistant, and offer multiple seasons of interest. Walker’s Low Nepeta Catmint Plant checked every box. It also holds the Royal Horticultural Society’s Award of Garden Merit. These accolades are not handed out lightly. They confirm what gardeners have known for years. This plant is the real deal.

Not Your Average Catmint

There are many catmints on the market. Some are floppy. Some bloom for only a few weeks. Some reseed aggressively and become nuisances. Walker’s Low Nepeta Catmint Plant avoids all these pitfalls. It has a naturally mounded habit that stays upright without staking. Its bloom period stretches from late spring well into autumn. It is sterile, so it will not seed around your garden uninvited. The foliage is aromatic with a pleasant minty scent that deer and rabbits find distasteful. The flowers are a soft lavender-blue that blends beautifully with almost any color scheme.

Ideal Growing Conditions

Sun Requirements

Full sun is best for Walker’s Low Nepeta Catmint Plant. Aim for at least six hours of direct sunlight daily. In the hottest southern climates, a bit of afternoon shade is appreciated and can prevent the foliage from scorching in July and August. Too much shade leads to leggy growth and fewer flowers. The plant will survive in part shade but it will not thrive. You will get floppy stems and a fraction of the blooms. If you have a sunny spot, this plant will reward you handsomely.

Soil Preferences

Good drainage is non-negotiable. This plant hates wet feet. Heavy clay soil that stays soggy after rain will cause root rot. If you have clay, amend it generously with compost, coarse sand, or fine gravel before planting. A slightly alkaline to neutral pH is ideal. The plant tolerates poor, rocky, or sandy soils beautifully. In fact, rich soil can encourage lush foliage at the expense of flowers. Lean soil produces stronger stems and more blooms. Don’t baby this plant with fancy soil mixes. It prefers life on the lean side.

Water Needs

Water regularly during the first growing season to establish a deep root system. Once established, Walker’s Low Nepeta Catmint Plant is remarkably drought tolerant. Its deep taproot seeks out moisture far below the surface. In most regions, rainfall alone is sufficient after year one. During extended dry spells in summer, a deep soaking every two to three weeks keeps it looking fresh. Avoid frequent shallow watering. That encourages shallow roots and reduces drought tolerance. Overwatering is the fastest way to kill this plant.

Climate Adaptability

This catmint thrives in USDA zones four through nine. It handles cold winters with ease, dying back to the ground and returning vigorously in spring. In zone four, a light mulch after the ground freezes provides extra insurance. In zones eight and nine, it may stay semi-evergreen through mild winters. It tolerates humidity better than many silver-leaved plants but still prefers good air circulation. High heat combined with high humidity can occasionally trigger fungal issues. Proper spacing helps prevent this.

Planting and Establishment

When to Plant

Spring and early fall are the optimal planting times. Spring planting gives the roots all summer to establish before winter. Fall planting works well in zones six and warmer, provided you plant at least six weeks before the ground freezes. Avoid planting in the heat of summer unless you can commit to diligent watering. Container-grown plants can technically go in the ground any time the soil is workable, but they will need extra attention during temperature extremes.

Spacing Guidelines

Space plants eighteen to twenty-four inches apart. This allows for their mature spread and ensures good air circulation. Crowded plants are more susceptible to powdery mildew and other fungal diseases. If you are creating a mass planting or hedge effect, you can space them slightly closer at fifteen inches. They will knit together quickly. For container growing, choose a pot at least twelve inches wide and deep. One plant per pot is plenty.

Planting Technique

Dig a hole twice as wide as the root ball but no deeper. Loosen the soil at the bottom and sides. Gently remove the plant from its pot. If the roots are circling, tease them apart with your fingers. Place the plant so the crown sits at soil level. Backfill with native soil mixed with a handful of compost. Firm gently to eliminate air pockets. Water thoroughly to settle the soil. Apply a thin layer of mulch, keeping it away from the crown. Gravel or crushed stone mulch looks great and reflects heat back to the plant.

First Season Care

The first year is all about root development. Water deeply once a week during dry spells. Don’t fertilize at planting time. The plant doesn’t need it and excess nitrogen promotes weak growth. Pinch back the growing tips once or twice in early summer to encourage bushier growth. This delays flowering slightly but produces a fuller plant. Remove any flower spikes that form in the first few weeks to direct energy to roots. By late summer, let it bloom freely.

Ongoing Maintenance

The Chelsea Chop

Around late May or early June, when the first flush of flowers begins to fade, give your Walker’s Low Nepeta Catmint Plant a haircut. This technique, known as the Chelsea Chop, involves cutting the entire plant back by about half. It seems brutal, but it works wonders. The plant responds with fresh, compact growth and a second heavy bloom cycle that lasts into fall. Without this cut, the center of the plant can open up and get woody. The chop keeps it dense and floriferous. Use clean, sharp shears. Cut just above a set of leaves.

Deadheading for Continuous Blooms

If you prefer not to do a hard chop, regular deadheading works too. Snip off spent flower spikes just above the next set of buds. This prevents seed formation and encourages repeat blooming. It is more time consuming than the Chelsea Chop but gives you more control over the plant’s shape. Some gardeners do a combination. They deadhead the first flush, then do a light shear in midsummer. Experiment to see what fits your schedule.

Dividing Mature Clumps

Every three to four years, the center of the clump may become woody and less productive. Spring is the best time to divide. Dig up the entire plant. Use a sharp spade or knife to cut the root ball into sections, each with healthy roots and shoots. Discard the woody center. Replant the vigorous outer sections at the same depth. Water well. Division rejuvenates the plant and gives you free plants to share or expand your garden. Fall division works in mild climates but spring is safer in cold zones.

Winter Care

In late fall, after several hard frosts, the foliage will die back. You can cut the dead stems to the ground anytime before new growth emerges in spring. Some gardeners leave the stems standing for winter interest and to protect the crown. The dried seed heads catch frost beautifully. If you leave them, cut back in early spring before new growth starts. In cold zones, a light layer of shredded leaves or straw over the crown after the ground freezes provides extra insulation. Remove it gradually in spring.

Design Ideas and Companions

Classic Pairings

The soft lavender-blue of Walker’s Low Nepeta Catmint Plant is a designer’s dream. It pairs beautifully with roses. The mounded habit hides the bare knees of rose bushes while the colors harmonize. Try it with pink shrub roses, yellow floribundas, or white climbers. It also shines alongside salvias, particularly the deep blue ‘May Night’ or hot pink ‘Hot Lips’. The combination of spiky salvias and billowy catmint creates wonderful texture contrast. Ornamental grasses like fountain grass or blue fescue echo its form while adding movement.

Color Combinations

For a cool, soothing palette, combine catmint with white coneflowers, blue veronicas, and silver artemisia. For high contrast, plant it with hot colors like red hot pokers, orange butterfly weed, or yellow coreopsis. The blue flowers cool down the heat. In a pastel garden, pair it with pink penstemon, lavender phlox, and white shasta daisies. The gray-green foliage acts as a neutral backdrop that makes neighboring colors pop. It truly works with everything.

Garden Styles

This plant fits seamlessly into cottage gardens, where its informal habit feels right at home. In Mediterranean gardens, its drought tolerance and silver foliage look authentic alongside lavender, rosemary, and thyme. In modern landscapes, mass plantings create strong geometric drifts of color. It excels in rock gardens where its drainage needs are naturally met. Pollinator gardens benefit from its long bloom season. Even formal gardens can use it as a clipped edging plant with regular shearing.

Container Combinations

Walker’s Low Nepeta Catmint Plant thrives in containers. Use a well-draining potting mix with added perlite or grit. Pair it with trailing plants like calibrachoa or sweet potato vine. Add a thriller like purple fountain grass or a dwarf conifer for height. The catmint fills the middle layer beautifully. Containers need more frequent watering than in-ground plants. Check daily in hot weather. Fertilize monthly with a balanced liquid fertilizer at half strength. Overwinter pots in an unheated garage in cold climates.

Troubleshooting Common Issues

Floppy Growth

If your plant flops open in the center, it usually means too much shade, too much water, or too rich soil. Move it to a sunnier spot. Cut back on watering. Stop fertilizing. The Chelsea Chop in early summer prevents this by promoting shorter, sturdier stems. Some gardeners use peony rings or grow-through supports placed early in the season. The supports disappear into the foliage as it grows.

Powdery Mildew

This fungal disease appears as a white powdery coating on leaves. It thrives in humid conditions with poor air circulation. Space plants properly. Water at the base, not overhead. Morning sun helps dry foliage quickly. If mildew appears, remove affected leaves. Spray with a homemade solution of one tablespoon baking soda plus one teaspoon horticultural oil per gallon of water. Neem oil also works. Severe cases may require cutting the plant back hard. It will regrow clean.

Root Rot

Yellowing leaves, wilting despite moist soil, and a foul smell indicate root rot. This is almost always caused by poor drainage. If caught early, dig up the plant, trim away rotted roots, and replant in a better location with improved drainage. Prevention is far easier than cure. Plant in raised beds or mounds if your soil is heavy. Use gravel mulch instead of organic mulch which holds moisture against the crown.

Lack of Flowers

If your Walker’s Low Nepeta Catmint Plant produces lots of leaves but few flowers, check three things. Is it getting enough sun? Six hours minimum. Is the soil too rich? Stop fertilizing. Is it overcrowded? Divide or thin nearby plants. Sometimes a hard prune in early spring stimulates flower production. Cut back to six inches as new growth emerges. This resets the plant and often triggers heavy blooming.

Pest Problems

Catmint is remarkably pest resistant. The aromatic oils deter most insects. Occasionally aphids may cluster on new growth. Blast them off with a strong jet of water. Spider mites can appear in hot, dry weather. Increase humidity with regular misting. Leafhoppers sometimes feed on the undersides of leaves but rarely cause serious damage. Deer and rabbits avoid it entirely. If you see cats rolling in it, that’s normal. The nepetalactone compound affects about seventy percent of cats. It doesn’t harm the plant.

Propagation Methods

Division

As mentioned earlier, division is the easiest and most reliable method. Do it in early spring as new growth appears. Dig the clump. Cut into sections with a sharp knife or spade. Each division needs roots and at least three to five shoots. Replant immediately. Water well. Keep evenly moist until established. Divisions often bloom the same year. This is my preferred method because it rejuvenates the parent plant at the same time.

Stem Cuttings

Take softwood cuttings in late spring or early summer. Choose non-flowering stems four to six inches long. Cut just below a leaf node. Remove lower leaves. Dip the cut end in rooting hormone. Insert into moist perlite or sand. Cover with a plastic bag to maintain humidity. Place in bright, indirect light. Roots form in three to four weeks. Transplant to individual pots. Grow on until fall, then plant out or overwinter in a cold frame.

Layering

This low-effort method works well because catmint stems often root where they touch the ground. In spring, pin a low stem to the soil with a landscape staple or rock. Cover the contact point with soil. Keep moist. By fall, roots will have formed. Cut the new plant from the mother and transplant. This is a great way to fill in gaps in a mass planting without buying new plants.

Seed Considerations

Walker’s Low Nepeta Catmint Plant is a sterile hybrid. It does not produce viable seed. Any seedlings that appear nearby will be from other catmint varieties in your garden or the neighborhood. They will not come true to type. If you want more of this exact plant, you must propagate vegetatively through division or cuttings. This sterility is actually a benefit. You never have to worry about it becoming weedy.

Seasonal Care Calendar

Spring

March to April: Cut back dead stems to ground level. Apply a thin layer of compost around the base. Divide congested clumps. Plant new specimens. Water if dry.

May: Pinch back growing tips for bushier growth. Watch for aphids on new growth. Apply peony rings if needed for support.

Summer

June: First flush of blooms peaks. Perform Chelsea Chop as flowers fade. Deadhead regularly if not chopping. Water during dry spells.

July to August: Second bloom cycle begins. Monitor for spider mites in heat. Water deeply but infrequently. Enjoy the pollinator show.

Fall

September to October: Final blooms continue until hard frost. Stop deadheading to allow some winter structure. Reduce watering as temperatures cool.

November: After several hard frosts, cut back to ground or leave standing for winter interest. Apply light mulch in cold zones.

Winter

December to February: Dormant period. No care needed. Plan next year’s companions. Order divisions from friends. Dream of lavender-blue clouds.
