Lavender, a woody perennial known for its aromatic purple flowers, thrives for years when planted alongside certain common flowers. Master gardener Stacy Ling emphasizes that lavender “performs and looks its best” with the “right companions.” Planting lavender alone often results in a short bloom period, but companion planting extends the season, improves plant health, and creates a cohesive garden design.
Why Companion Planting Matters
Companion planting is not just about aesthetics. The right plant combinations ensure similar growing conditions, improved airflow, better pollinator attraction, and reduced maintenance. Stacy warns that the “biggest mistake” is pairing lavender with plants that need rich soil, frequent watering, or shade, which can kill the lavender.
Best Companion Plants for Lavender
Thyme is a top choice, as Stacy says, “Thyme and lavender are practically made for each other. Both love full sun, excellent drainage, lean soil, and less frequent watering.” She especially loves creeping thyme for its weed suppression and fine texture.
Roses are another favorite. Stacy notes, “One of my favourite companions for lavender is roses; you just can’t beat it.” Lavender softens the base of rose shrubs, adding fragrance and color contrast.
Nepeta, or catmint, is praised for its complementing foliage and long bloom time. Stacy states, “If I had to pick one perennial companion that always works with lavender, it’s nepeta.”
Zinnias are “amazing companions” that attract pollinators and provide “armloads of flowers.” Stacy explains, “I especially love pairing them with lavender because they begin hitting their stride just as lavender’s first flush starts to fade, helping keep the garden colourful for months.”
