Excellent Plant Companions for Lavender
Selecting plants that thrive alongside lavender can enhance your garden's appeal and health. The key is to match their preferences for sunlight, soil drainage, and water needs. Lavender, with its aromatic foliage and striking purple blooms, pairs beautifully with a range of herbs, flowers, and even some vegetables that share its love for hot, dry conditions and well-drained soil.
- Companion plants should share lavender's need for sun and drainage.
- Herbs and drought-tolerant flowers are ideal partners.
- Consider foliage contrast and bloom times for visual interest.
- Avoid plants that require consistently moist soil.
When considering what plants go with lavender, think about creating a cohesive look and a supportive microclimate. Plants with silver or grey foliage, like rosemary, sage, and Artemisia, echo lavender's own muted tones and thrive in similar conditions. Their textures provide a beautiful contrast to lavender's spikes. Similarly, plants that flower at different times, or offer a different colour palette, can extend the season of interest in your borders. For instance, pairing lavender with plants that bloom in yellow or white can create a classic, harmonious display.
It's crucial to remember lavender's specific needs. It demands excellent drainage and dislikes waterlogged roots, which can lead to root rot. Therefore, any companion plants must tolerate similar conditions. This immediately rules out many moisture-loving plants. Instead, focus on those that appreciate a sunny spot and can handle periods of dryness once established. This shared tolerance is the foundation of successful companion planting with lavender.
Choosing Plants Based on Companion Needs
The success of companion planting with lavender hinges on matching environmental requirements. Lavender plants, particularly popular varieties like English lavender (Lavandula angustifolia), prefer full sun and poor to moderately fertile soil that drains exceptionally well. French lavender (Lavandula stoechas) and Spanish lavender can tolerate slightly more moisture but still require good drainage. When selecting partners, look for plants that also enjoy these conditions. This includes many Mediterranean herbs, succulents, and certain ornamental grasses.
Consider the mature size of your chosen plants to avoid overcrowding, which can impede air circulation and increase the risk of fungal diseases for lavender. A good rule of thumb is to allow at least 30-60 cm (1-2 feet) spacing between plants, depending on their final size. This ensures that each plant has adequate room to grow and that light and air can penetrate the planting scheme effectively. Proper spacing is vital for maintaining plant health and achieving the best visual impact.
The soil pH is another factor. Lavender generally prefers slightly alkaline to neutral soil (pH 6.5-7.5). While most common garden plants are adaptable, those that require very acidic soil might not be the best companions. It’s worth checking the specific needs of any plant you consider introducing to a lavender bed.
Ideal Companion Plants for Lavender
When you are wondering what plants go with lavender, the most straightforward and successful pairings often involve other drought-tolerant, sun-loving plants. These companions not only share similar growing requirements but also offer aesthetic contrast or complementary scents.
Herbs as Lavender Companions
Many herbs are natural partners for lavender due to their shared love for sun and well-drained soil. Their silvery foliage and varied textures create a beautiful tapestry with lavender. Consider these options:
- Rosemary (Rosmarinus officinalis): Its woody stems and needle-like leaves provide a strong vertical element and fragrant aroma that complements lavender wonderfully. Both plants require excellent drainage and full sun.
- Thyme (Thymus spp.): Low-growing thymes, especially creeping varieties, can act as a beautiful ground cover around lavender. They tolerate dry conditions and poor soil, making them ideal companions.
- Sage (Salvia officinalis): Many varieties of sage offer attractive grey-green foliage and spikes of flowers that pair well with lavender. They share the need for good drainage and plenty of sun.
- Oregano (Origanum vulgare): Particularly the ornamental varieties with trailing habit, oregano is hardy and adaptable, thriving in similar conditions to lavender.
- Santolina (Cotton Lavender): This shrubby herb offers striking silver foliage and button-like yellow flowers, providing excellent colour and texture contrast.
Flowering Plants for Contrast and Colour
Adding flowering plants can introduce vibrant colour and extend the blooming season of your lavender planting. Focus on species that also prefer drier conditions:
- Echinacea (Coneflower): With their sturdy stems and daisy-like blooms in shades of pink, purple, and white, coneflowers add height and colour. They are drought-tolerant once established.
- Achillea (Yarrow): Yarrow's flat-topped flower clusters in shades of yellow, pink, and red offer a different form and bloom time, and it thrives in sunny, dry spots.
- Coreopsis: These cheerful, daisy-like flowers in bright yellow or orange are tough and adaptable, tolerating dry spells and poor soil once established.
- Gaillardia (Blanket Flower): Known for their vibrant, often bi-coloured red and yellow petals, these plants are exceptionally drought-tolerant and love full sun.
- Sedum (Stonecrop): Succulent-like leaves and late-summer to autumn flowers make sedums excellent companions. They store water, making them highly drought-tolerant and perfect for sunny, well-drained borders.
- Delphinium (in drier climates or raised beds): While some delphiniums prefer more moisture, certain varieties, especially when planted in well-draining soil and provided with adequate space, can coexist.
Shrubs and Grasses for Structure
For larger borders or to add structure throughout the year, consider these options:
- Hebe: Many hebe varieties are compact shrubs with attractive foliage and flower spikes that enjoy similar conditions to lavender.
- Shrub Roses: Especially those bred for drought tolerance and disease resistance. Their blooms can offer a beautiful contrast to lavender's purple.
- Ornamental Grasses: Varieties like *Festuca glauca* (Blue Fescue) offer striking blue foliage, while taller grasses such as *Calamagrostis x acutiflora* 'Karl Foerster' provide vertical interest and movement.
To ensure plants don't compete excessively for nutrients and water, consider amending the soil with grit or perlite when planting, especially if your garden soil tends to retain moisture. This improves drainage for all plants involved.
What to Avoid Planting Near Lavender
Understanding what plants go with lavender also means knowing which ones to keep separate. Planting the wrong neighbours can lead to struggling plants, increased pest problems, and a less attractive garden. The primary concern is moisture. Lavender absolutely detests having 'wet feet' – consistently soggy soil that can quickly lead to root rot, a common killer of the plant.
Plants Requiring High Moisture
Any plant that thrives in damp conditions or needs regular watering that keeps the soil consistently moist should be avoided. This includes many popular garden favourites:
- Most types of Hostas
- Astilbes
- Ferns (unless specifically a very drought-tolerant variety, which is rare)
- Ligularia
- Rodgersia
- Primulas and Polyanthus
- Vegetables that require significant, consistent watering such as tomatoes or cucumbers, especially if they are planted in the same bed without significant barriers or drainage management.
Plants That Need Rich, Heavy Soil
Lavender prefers lean, even poor soil. Overly rich, heavily manured soil can lead to lush, weak growth that is more susceptible to disease and produces fewer flowers. Plants that demand highly fertile, nutrient-rich conditions might thrive at the expense of the lavender, or vice versa, creating an imbalance.
Avoid planting tender perennials or annuals that require a longer growing season and protection from frost. While lavender is hardy, these plants might not survive the same conditions and could require different care routines that conflict with lavender's needs.
It is also worth noting that while lavender is a fantastic pollinator attractor, pairing it with plants that are highly susceptible to common pests like aphids or slugs could inadvertently create a haven for these pests to spread to your lavender, or vice versa, if conditions become too humid due to dense planting.
The most successful lavender companions are those that are as unfussy about soil and water as lavender itself.
Consider the overall garden design. If you have a specific area designed for moisture-loving plants, keep it separate from your lavender. Creating distinct zones with different soil and watering regimes will ensure all your plants are happy and healthy.
Designing Your Lavender Planting Scheme
Creating a beautiful and functional planting scheme with lavender involves more than just selecting companion plants; it's about visual harmony, seasonal interest, and practicality. When you think about what plants go with lavender, consider the overall aesthetic you wish to achieve.
Visual Harmony and Colour Palettes
Lavender's iconic purple blooms and silvery-grey foliage lend themselves to several classic colour combinations. For a serene and sophisticated look, pair lavender with plants featuring white, cream, or pale pink flowers and silver foliage. Think of white-flowered herbs like white sage or lavender cotton (Santolina), or ornamental grasses like blue fescue. These combinations create a cool, calming atmosphere that is reminiscent of Mediterranean landscapes.
For a bolder statement, introduce contrasting colours. Bright yellow flowers, such as those from Coreopsis or Yarrow, create a vibrant, sunny display against the purple. Deep reds and oranges from plants like Gaillardia can also provide striking contrast. When using strong colours, ensure they are balanced to avoid overwhelming the subtle beauty of the lavender.
Textural Interest
Beyond colour, texture plays a crucial role. Combine the upright spikes of lavender with the mounding shapes of herbs like thyme and sage, the flat flower heads of yarrow, or the feathery plumes of ornamental grasses. Plants with fine, wispy foliage can soften the edges of a planting, while those with bold, architectural leaves can provide a strong focal point elsewhere in the garden. This mix of forms prevents a planting from looking flat and adds depth.
Seasonal Interest
To ensure your garden looks appealing throughout the year, select companions that offer interest at different times. Lavender typically blooms from late spring through summer. Consider planting spring-flowering bulbs like alliums (which also tolerate dry conditions) beneath or around lavender, providing early colour. For late-season interest, choose plants that bloom in late summer or autumn, such as many varieties of Sedum or late-flowering ornamental grasses.
Even in winter, the structure provided by woody herbs, evergreen shrubs, and ornamental grasses can offer a pleasing silhouette. Planting companions that have interesting seed heads or persistent foliage can maintain visual appeal long after the main blooming season has passed.
For a truly integrated design, consider the mature size of all plants. Group plants with similar water needs together, but ensure there's enough space for air circulation around each specimen, especially around lavender, to prevent fungal issues.
By thoughtfully selecting plants that share lavender's love for sun and drainage, and by considering colour, texture, and seasonal bloom, you can create a garden that is not only beautiful but also healthy and ecologically balanced.
