Purple Flowers That Look Like Lavender

If you love the look of lavender but want more options for your garden, you’re in the right place. Many purple-flowering plants offer a similar visual appeal to lavender, with varying bloom shapes and growing needs. This guide will show you the best purple flowers that look like lavender, helping you choose the perfect alternatives for your climate and garden style.

We will cover plants with spiky blooms, silvery foliage, and that wonderful fragrance. You’ll learn how to care for them and where to plant them for the best effect.

This list focuses on plants that share lavender’s iconic purple hue and often its growth habit. While not all are true lavenders (Lavandula), they provide a comparable beauty and charm.

Russian Sage (Perovskia Atriplicifolia)

Russian sage is a top contender. It boasts airy spikes of tiny, lavender-blue flowers and aromatic, silvery-gray foliage that is very similar to lavender. It’s extremely tough, drought-tolerant, and blooms from mid-summer into fall.

Height: 3-4 feet tall and wide.
Sun Needs: Full sun.
Hardiness: USDA zones 4-9.
Key Difference: It has a more open, wispy growth habit compared to lavender’s denser mound.

Catmint (Nepeta)

Catmint is a garden workhorse with spikes of small purple flowers that look remarkably like lavender. It’s incredibly easy to grow, blooms profusely, and its gray-green foliage adds lovely texture. The ‘Walker’s Low’ variety is exceptionally popular.

Height: 1-2 feet tall, often wider.
Sun Needs: Full sun to partial shade.
Hardiness: USDA zones 3-8.
Key Difference: Flowers are often a softer purple and the plant has a more sprawling habit.

Salvia (Salvia Nemorosa Or Salvia Officinalis)

Many salvias, especially the perennial types like ‘May Night’ or ‘Caradonna’, produce dense spikes of purple flowers. They are magnets for pollinators and have a long blooming period, especially with deadheading.

Height: 1-3 feet tall, depending on variety.
Sun Needs: Full sun.
Hardiness: Varies by species (often zones 4-8).
Key Difference: Foliage is typically green, not silvery, and flower spikes are very dense.

Hyssop (Agastache)

Often called hummingbird mint, hyssop features tall, slender spikes of tubular purple flowers. The foliage is fragrant when brushed, and it’s a superb plant for attracting hummingbirds and butterflies to your yard.

Height: 2-4 feet tall.
Sun Needs: Full sun.
Hardiness: USDA zones 5-10, depending on variety.
Key Difference: Flowers are more tubular and spaced out on the spike, and leaves are green and anise-scented.

English Lavender (Lavandula Angustifolia)

Of course, true lavender itself is the standard. English lavender is the most common and hardy type, known for its sweet fragrance and compact growth. It’s the classic choice for hedges, borders, and drying.

Height: 1-2 feet tall and wide.
Sun Needs: Full sun.
Hardiness: USDA zones 5-8.
Key Difference: This is the real thing, offering the quintessential lavender scent and form.

Mexican Bush Sage (Salvia Leucantha)

For warmer climates, this sage offers stunning velvety purple and white flower spikes. It blooms in late summer and fall when many other flowers are fading, providing crucial late-season color.

Height: 3-4 feet tall and wide.
Sun Needs: Full sun.
Hardiness: USDA zones 8-11 (often grown as an annual in cooler zones).
Key Difference: Flowers are fuzzy and bi-colored, with a distinctive tropical look.

Choosing the Right Lavender Look-Alike for Your Garden

Selecting the best plant depends on more than just color. Consider your local climate, soil, and the specific role you want the plant to play in your landscape design.

Consider Your Climate And Hardiness Zone

Your USDA hardiness zone is the most important factor. True lavender prefers zones 5-8 with dry winters. If you live in a humid area or a very cold zone, alternatives like Russian sage (zone 4) or catmint (zone 3) are better choices.

For Cold Climates (Zones 3-5): Focus on Catmint, Russian Sage, and some hardy Salvias.
For Hot & Humid Climates (Zones 7-10): Consider Mexican Bush Sage, some Hyssop varieties, and French lavender (Lavandula dentata), which tolerates more humidity.

Assess Sunlight And Soil Conditions

Almost all lavender look-alikes demand full sun—at least 6-8 hours of direct light daily. Without it, they will become leggy and bloom poorly. Soil drainage is equally critical.

These plants despise wet feet. You must have well-draining soil. If you have heavy clay, you will need to amend it.

Test your soil drainage by digging a hole and filling it with water. If it drains slower than an inch per hour, you need to improve it.
Amend planting beds with 2-3 inches of coarse sand or fine gravel and compost to improve texture and drainage.
Consider planting in raised beds or mounds to ensure excess water flows away from the root crown.

Decide On Garden Purpose And Aesthetic

Think about how you want to use the plant. Do you want a low border, a focal point, or a pollinator patch? This will guide your height and variety selection.

For Low Borders or Edging: Choose compact English Lavender, dwarf Catmint, or low-growing Salvia.
For Mid-Border Structure: Russian Sage, taller Salvias, and Hyssop work perfectly.
For Sensory Gardens: Prioritize fragrant types like Lavender, Hyssop, and Catmint.
For Cutting Gardens: English Lavender and many Salvias are excellent for fresh or dried arrangements.

Planting and Caring for Your Purple Blooms

Proper planting and simple maintenance are key to keeping your lavender substitutes healthy and floriferous for years to come. The care is similar for most of these drought-tolerant perennials.

Step-by-Step Planting Guide

Follow these steps to give your new plants the best possible start. The best time to plant is in the spring or early fall, when temperatures are mild.

Choose a location with excellent drainage and full sun.
Dig a hole twice as wide as the plant’s root ball but no deeper.
Gently loosen the roots if the plant is pot-bound.
Place the plant in the hole, ensuring the top of the root ball is level with the surrounding soil.
Backfill with the native soil, optionally mixed with a little compost. Avoid rich fertilizers.
Water thoroughly to settle the soil around the roots.
Apply a thin layer of gravel or crushed stone as mulch to suppress weeds and keep foliage dry.

Watering And Fertilizing Needs

Overwatering is the fastest way to kill these plants. They are drought-tolerant once established and prefer to be on the dry side.

Watering Schedule: Water deeply once or twice a week after planting until established (about one growing season). Then, rely on rainfall, only providing supplemental water during extended droughts.
Fertilizing: These plants thrive in moderate to poor soil. Excessive fertilizer leads to weak, floppy growth and fewer flowers. A light application of a balanced, slow-release fertilizer in early spring is usually sufficient, or simply top-dress with compost.

Pruning And Deadheading For Best Results

Regular pruning maintains shape, encourages bushier growth, and promotes more blooms. The timing and method vary slightly.

Pruning Lavender and Woody Subshrubs

For plants like lavender and Russian sage that develop a woody base, pruning is crucial. Never cut back into old, bare wood, as it may not regrow.

In Spring: Once you see new green growth at the base, prune back the entire plant by about one-third to one-half, shaping it into a mound. Always leave some green leaves on each stem.
After Bloom: Deadhead spent flower spikes to encourage a possible second flush.

Pruning Herbaceous Perennials

For plants like catmint and salvia that die back to the ground, the process is simpler.

In Early Spring: Cut all old stems down to the ground before new growth emerges.
During Summer: Shear catmint back by half after its first major bloom to encourage a tidy rebloom.

Design Ideas Using Lavender Look-Alikes

These versatile plants can be used in countless ways to create beautiful, resilient gardens. Their structure and color make them excellent design elements.

Creating A Fragrant Border Or Hedge

Use a single type of plant, like English lavender or a compact catmint, to create a low, fragrant border along a walkway or garden edge. Plant them 12-18 inches apart (depending on variety) so they grow together into a continuous line. This defines spaces and releases scent when brushed against.

Pollinator Garden Combinations

Combine several lavender look-alikes for a pollinator paradise. Pair purple Russian sage with yellow coreopsis, white Shasta daisies, and orange coneflowers. The varying heights and textures create visual interest, and the long bloom times provide a consistent food source for bees, butterflies, and hummingbirds.

Xeriscaping And Drought-Tolerant Landscaping

These plants are stars in water-wise gardens. Group them with other Mediterranean plants like ornamental grasses, sedum, yucca, and thyme. Use gravel mulch to conserve moisture, reduce weeds, and complement the silvery foliage. This creates a sustainable, low-maintenance landscape that thrives with minimal supplemental water.

Common Problems and Solutions

Even tough plants can encounter issues. Here are the most common problems and how to fix them.

Preventing Root Rot And Fungal Issues

Root rot from poor drainage is the number one threat. Signs include wilting, yellowing leaves, and stunted growth, even when soil seems moist. Prevention is the only cure.

Ensure perfect drainage at planting time.
Avoid overhead watering; use soaker hoses or water at the base.
Space plants adequately for good air circulation.
Remove and discard any plants that succumb to rot to prevent it from spreading.

Managing Pests Like Aphids And Spider Mites

These pests are occasional visitors, especially in dry, dusty conditions. They suck sap from leaves, causing stippling or distortion.

Spray strong jets of water from a hose to dislodge pests.
Introduce beneficial insects like ladybugs or lacewings.
For severe infestations, use insecticidal soap or neem oil, following label instructions carefully.

Dealing With Leggy Growth And Lack Of Blooms

If your plants are stretched out and not flowering, the cause is usually simple.

Insufficient Sun: They need full sun. If they’re shaded, consider moving them.
Too Much Fertilizer: Excess nitrogen promotes leafy growth at the expense of flowers. Stop fertilizing and let the soil lean out.
Improper Pruning: A lack of spring pruning can lead to woody, unproductive plants. Be sure to prune at the correct time.

FAQ: Purple Flowers That Look Like Lavender

Here are answers to some common questions about these beautiful plants.

What Is The Closest Flower To Lavender?

Russian sage (Perovskia) is often considered the closest visual match due to its fine, silvery foliage and long spikes of small purple flowers. Catmint (Nepeta) is another very close alternative, especially in growth habit and bloom shape.

What Purple Plant Looks Like Lavender But Isn’t?

Many plants fit this description. Common ones include Russian sage, catmint, salvia ‘May Night’, hyssop (Agastache), and Mexican bush sage. Each has its own unique characteristics but offers a similar purple, spiky bloom effect in the garden.

How Can I Tell If My Plant Is Lavender Or A Look-alike?

Examine the foliage and scent. True lavender has narrow, silvery-gray leaves that are highly aromatic when crushed, releasing its classic calming fragrance. Look-alikes often have green or differently shaped leaves, and their scent may be minty (catmint), sage-like (salvia), or different altogether.

Which Lavender Alternative Is The Easiest To Grow?

Catmint (Nepeta) is arguably the easiest. It is extremely cold-hardy, tolerates a wider range of soils, blooms prolifically for months, and requires minimal care. It’s rarely bothered by pests or diseases, making it a foolproof choice for beginners.

Can I Use These Plants For Cooking Like Lavender?

You must be very cautious. Only true culinary lavender (Lavandula angustifolia varieties like ‘Hidcote’ or ‘Munstead’) should be used in food. Most look-alikes are not considered edible and could cause stomach upset. For example, salvia officinalis is common sage, used in cooking, but Russian sage or catmint are not for culinary use. Always positively identify a plant before consuming any part of it.

Adding purple flowers that look like lavender to your garden expands your options for color, texture, and fragrance. By considering your local conditions and the specific traits of each plant, you can enjoy the lavender aesthetic with plants perfectly suited to thrive in your space. With proper planting and simple care, these resilient perennials will provide beauty and interest for many seasons to come.
