A Guide to Companion Planting: 9 Flowers That Go Well with Lilies

Choosing the right partners for your lilies is the secret to a truly breathtaking garden. The perfect companion plants do more than just look pretty; they support your lilies' health, extend the season of colour, and create a lush, complete look. 

This guide will walk you through the best perennials, annuals, and shrubs to pair with all types of lilies. We will focus on matching colours and textures, and share practical tips for a garden that flourishes beautifully in Singapore’s climate.

Perennials are the backbone of a well-designed garden, returning year after year to provide structure and reliable colour. When paired with lilies, they create a timeless and low-maintenance display. The key is to choose perennials that share similar growing requirements, plenty of sun and well-drained soil, but offer contrasting forms and textures.

1. Creating Classic Combinations with Peonies and Irises

Peonies and irises are classic garden staples that form a perfect partnership with lilies. Peonies, with their large, fluffy, and often fragrant blooms, provide a wonderful textural contrast to the sleek, trumpet-shaped flowers of lilies. They typically bloom just before or as the first Asiatic lilies are opening, creating a seamless transition of colour. Irises, particularly the tall bearded varieties, offer a unique architectural form with their sword-like leaves and intricate flowers. 

Their upright foliage provides a strong vertical element that complements the tall stems of lilies, and they share the same love for sunny, well-drained spots. This combination ensures your garden bed has magnificent focal points throughout the early and mid-summer seasons.

2. Low-Growing Perennials to Complement Lily Stems

One of the best design strategies for lilies is to plant low-growing perennials at their base. This technique effectively hides the "bare legs" of the lily stalks, creating a fuller and more polished look. Lady's Mantle (Alchemilla mollis) is an excellent choice, with its soft, scalloped leaves that beautifully catch water droplets and its frothy, chartreuse flowers that complement any lily colour. 

Perennial Geraniums, also known as Cranesbill, are another fantastic option. They form neat mounds of attractive foliage and produce a profusion of delicate flowers over a long period. Columbines (Aquilegia) bring a whimsical charm with their intricate, spurred flowers that seem to dance in the breeze, filling the space below the towering lily blooms with grace and colour.

3. Pairing with Other Summer-Blooming Favourites

To keep your garden buzzing with life and colour throughout the summer, pair your lilies with other reliable bloomers. Garden Phlox, with its large, fragrant flower clusters, creates a lush backdrop for mid-season lilies. Salvia, particularly the spiky blue and purple varieties like 'May Night', provides a stunning vertical contrast to the shape of lily flowers and is adored by bees and butterflies. 

Coneflowers (Echinacea) are a hardy and popular choice, offering a daisy-like shape that stands out against the lily blooms. Their sturdy stems and long flowering season make them a dependable and attractive partner, ensuring your garden remains a vibrant hub for pollinators all summer long.

Choosing Annuals as Lily Companions

Annual flowers offer a wonderful sense of freedom and flexibility in the garden. Because they complete their life cycle in a single season, you can experiment with new colour schemes and designs every year. They are perfect for filling in gaps, providing continuous colour, and adding layers of texture around your perennial lilies.

4. The Best Annuals for Colour and Texture

In Singapore's tropical heat, it's important to choose annuals that are tough and resilient. These plants can provide a beautiful, season-long display alongside your lilies.

• Vinca (Periwinkle): This is a true champion in warm climates. Its glossy green leaves and cheerful flowers in shades of pink, white, and purple create a dense, low-growing mat that is perfect for suppressing weeds and providing ground cover around the base of your lilies.
• Cosmos: For a soft, airy, and romantic feel, Cosmos is an unbeatable choice. Its tall, slender stems are topped with delicate, daisy-like flowers that sway gracefully in the breeze. They can be planted amongst lilies to create a beautiful, meadow-like effect without casting too much shade.
• Alyssum: If you're looking for a fragrant and delicate edging plant, Sweet Alyssum is ideal. It produces a carpet of tiny, honey-scented flowers that will spill over the edges of your garden bed, softening the lines and creating a beautiful, low-maintenance border in front of your lilies.

5. Using Annuals to Fill Gaps

Annuals are the perfect solution for filling temporary gaps in your garden. You can sow their seeds or plant seedlings in early spring to fill the spaces where your lilies will later emerge. This ensures the garden bed looks full and colourful from the very beginning of the growing season. 

Once the lilies have finished their spectacular show and their foliage begins to fade, these hardworking annuals will continue to bloom, carrying the display of colour through the rest of the summer and into autumn. This strategic planting ensures there are no dull moments in your garden.

What to Plant with Different Types of Lilies

While many companion plants work well with lilies in general, tailoring your choices to the specific type of lily you are growing can elevate your garden design from lovely to truly exceptional. Different lilies have unique characteristics, from their bloom time and size to their fragrance and colour palette.

6. Companion Plants for Asiatic Lilies

Asiatic lilies are typically the first to bloom in early summer. They are known for their vibrant, upward-facing flowers in bold shades of yellow, orange, red, and pink, although they are usually unscented. Because they are early bloomers, they pair beautifully with plants that share a similar timeline. 

Consider planting them with Campanula (Bellflowers), whose charming blue or purple bell-shaped flowers create a lovely colour contrast. Early-blooming varieties of Salvia or Catmint (Nepeta) also work wonderfully, providing a soft haze of cool colour that makes the bright hues of the Asiatic lilies pop.

7. Companion Plants for Oriental Lilies

Oriental lilies are the dramatic showstoppers of the late-summer garden. They are famous for their huge, intoxicatingly fragrant flowers in shades of white, pink, and crimson. To complement their grand presence, choose companions that can handle the late-summer heat and won't compete with their spectacular blooms. 

Baby's Breath (Gypsophila) is a classic choice, creating a delicate, cloud-like effect that softens the large lily flowers. For a beautiful contrast in both colour and texture, plant them with Russian Sage (Perovskia). Its silvery foliage and spires of lavender-blue flowers create a cool and elegant backdrop for the rich colours of the Oriental lilies.

8. What to Plant with Daylilies (Hemerocallis)

It is important to note that daylilies are not "true lilies" from the Lilium genus, but their similar name and appearance mean they are often used in the same way in gardens. Daylilies are incredibly tough, reliable, and come in a vast range of colours. Their strappy, arching foliage provides texture even when the plant is not in bloom. 

They pair wonderfully with plants that offer a different flower shape and foliage form. Black-Eyed Susans (Rudbeckia) provide a cheerful, daisy-like flower that contrasts nicely with the trumpet shape of daylilies. Ornamental grasses, like Fountain Grass (Pennisetum), add movement and fine texture. For late-season interest, Sedum 'Autumn Joy' is a superb companion, as its succulent foliage and broccoli-like flower heads look great next to daylily leaves.

9. What to Plant with Calla Lilies (Zantedeschia)

Calla lilies are another plant often mistaken for a true lily. They are prized for their elegant, sculptural flowers and lush foliage. Unlike most true lilies that demand well-drained soil, Calla lilies prefer consistently moist conditions. 

Therefore, their ideal companions are other plants that thrive in similar environments. Hostas are a perfect partner, as their broad, textured leaves in shades of green, blue, and chartreuse create a stunning foliage display alongside the sleek Calla lily. Ferns, with their delicate and feathery fronds, also make an excellent companion, adding a layer of fine texture and reinforcing a lush, woodland feel.

Understanding the Role of Companion Plants for Lilies

When we talk about companion planting for lilies, we are looking at a partnership that goes far beyond surface-level beauty. While creating stunning visual combinations is a delightful goal, the right companion plants serve several practical purposes that help your lilies thrive. They work together to form a small, supportive ecosystem within your garden bed, ensuring healthier plants and a more dynamic display of flowers.

The benefits are numerous and significant. One of the most common challenges with lilies is their appearance after they have finished flowering. Their stems and foliage can start to look tired and yellow, which can detract from the garden's overall look. 

This is where companion plants play a crucial role by hiding this fading foliage. Furthermore, some companions can provide gentle physical support to tall lily stems, preventing them from flopping over in the wind or rain. Most importantly, selecting plants with shallow roots ensures they do not compete with the deep-rooted lily bulbs for water and nutrients. 

These low-growing plants also act as a living mulch, helping to keep the soil cool and moist, which lilies absolutely love. By choosing plants that bloom at different times, you can achieve a "succession of flowers," ensuring your garden remains vibrant from spring through to late summer.

Creating Beautiful Bouquets: Do Roses and Lilies Go Together?

There are many flowers that pair well with roses. The question of whether roses and lilies go together is one we hear often, and the answer is a resounding yes. In the world of floral design, this pairing is a timeless classic, celebrated for its elegance and symbolic meaning. 

Roses, representing love and passion, combined with lilies, which often symbolise purity and devotion, create a powerful and beautiful message in a bouquet. This combination is a favourite for weddings, anniversaries, and other significant occasions.

When creating a bouquet with roses and lilies, the key is balance. The large, dominant blooms of the lilies need to be balanced with the right type and number of roses. For a romantic look, pair fragrant Oriental lilies with lush, full-petaled garden roses. For a more modern arrangement, sleek Asiatic lilies can be combined with smaller spray roses. 

To complete the arrangement, add filler flowers and foliage. Delicate sprigs of Baby's Breath can fill in the gaps and add a touch of softness, while silver-dollar Eucalyptus provides beautiful texture, fragrance, and a contemporary feel.

Garden Design Ideas with Lilies

Beyond choosing the right plants, thinking about design principles like colour and texture will help you create a truly cohesive and professional-looking garden. Lilies are so versatile that they can fit into almost any garden style, from a formal, structured border to a relaxed and romantic cottage garden.

Designing for Colour Harmony

The colours you choose will set the entire mood of your garden. You can create different effects by playing with colour schemes.

• A Monochromatic Scheme: This creates a serene and sophisticated look. Imagine a garden bed filled with elegant white Oriental lilies, paired with the fluffy white flower panicles of Garden Phlox, and accented with the silvery, soft leaves of Lamb's Ear (Stachys byzantina).
• A Contrasting Scheme: For a bold and energetic feel, use colours that are opposite each other on the colour wheel. For example, plant vibrant orange Asiatic lilies alongside the deep, spiky blooms of a purple Salvia. The contrast will make both colours appear more intense and lively.
• An Analogous Scheme: This involves using colours that are next to each other on the colour wheel to create a gentle, harmonious effect. Pair soft pink Oriental lilies with perennials that have shades of lavender and pale blue, such as Campanula or Geranium 'Rozanne'.

Playing with Texture and Form

Texture is just as important as colour in garden design. A garden that uses a variety of textures is visually interesting even when nothing is in bloom. The bold, smooth petals and strong vertical stems of lilies provide a perfect opportunity to introduce contrasting forms. Pair them with fine-textured plants to create a soft, cloud-like effect; Baby's Breath or airy ferns are perfect for this. 

Alternatively, introduce spiky forms to create dynamic energy. The upright flower spikes of Salvia or Liatris (Blazing Star) provide a strong vertical contrast to the rounded lily blooms, drawing the eye upwards and adding a sense of rhythm to the planting.

What Not to Plant with Lilies

Just as important as knowing what to plant with lilies is knowing what to avoid. Choosing the wrong neighbours can lead to competition for resources, poor growth, and an increased risk of disease. Being mindful of what not to plant will help ensure your lilies remain healthy and beautiful for years to come.

The biggest threat to lilies is competition from overly aggressive plants. Avoid planting them with fast-spreading perennials or invasive ground covers, such as certain types of mint or Bishop's Weed (Aegopodium). 

These plants have vigorous root systems that can quickly spread and choke out the lily bulbs, robbing them of essential water and nutrients. It is also wise to avoid planting lilies next to large, dense shrubs that will cast too much shade, as lilies need at least six hours of direct sunlight per day to produce strong stems and abundant flowers.

Lilies are also susceptible to bulb rot if their roots sit in waterlogged soil. For this reason, you should avoid planting them with companions that require very wet or boggy conditions, such as Marsh Marigolds or Candelabra Primulas. 

Always group plants with similar water and soil requirements together. The golden rule for lilies is "sunny head, cool feet," which means they love sun on their flowers but prefer their roots to be shaded and cool in well-drained soil.

Conclusion On What Flowers Go Well With Lilies

In conclusion, successful companion planting for lilies is a thoughtful balance of art and science. It involves looking beyond just colour and considering the practical needs of the plants. The best companions will support your lilies by keeping their roots cool, hiding their fading foliage, and creating a continuous display of beauty in the garden. 

Perennials provide a reliable structure, while annuals offer the flexibility to experiment with new designs each year. By choosing the right partners, you can transform your garden into a stunning, healthy, and vibrant space that brings you joy all season long.

Also, avoid plants that require waterlogged soil, as most lilies need well-drained conditions to prevent bulb rot. Avoid planting them in the deep shade of large shrubs or trees.

Do Roses and Lilies Go Together?

Yes, roses and lilies go together beautifully, both in the garden and in bouquets. They are a classic and elegant pairing. In the garden, they share similar requirements for sun and well-drained soil. In floral arrangements, their contrasting shapes and rich symbolic meanings make them a timeless favourite.

What Perennials Look Good with Lilies?

Many perennials look wonderful with lilies. For classic combinations, try Peonies and Irises. For textural contrast, consider Phlox, Salvia, and Coneflowers (Echinacea). To cover the base of the lily stems, low-growing perennials like Lady's Mantle (Alchemilla mollis) and Cranesbill Geraniums are perfect.

How Do You Hide Lily Stems After They Bloom?

The best way to hide lily stems after they bloom is by using companion plants. Plant bushy perennials or annuals like Hostas, Ferns, Geraniums, or Cosmos around the base of the lilies.
