The fluttering of butterflies in your garden can be a delightful sight, their iridescent wings adding a splash of colour and vibrancy. Beyond their aesthetic appeal, butterflies, as well as bees and moths, are integral to the health of our ecosystem. They play an important role in pollination, helping plants to reproduce and contributing to biodiversity. As a gardener, you can support local butterfly populations by choosing the right plants for your garden. This guide will take you through the best plants to grow in your garden to attract and sustain native butterfly species in the UK.
The Importance of Native Plants
Native plants are not simply those that are endemic to a particular region. They play unique roles in their respective ecosystems and have adapted over thousands of years to local soils, climates, and wildlife. The word native in this context refers to plants that have evolved in a specific region, over long periods of time and without human intervention.

In the UK, native plants have evolved alongside native butterfly species. This has resulted in a mutualistic relationship where butterflies depend on certain plants for survival, and in turn, these plants depend on butterflies for pollination. This interdependence means butterflies are more likely to be attracted to and sustained by native plants, making them a key element in your butterfly-friendly garden.
Best Native Plants for Butterflies
Choosing the best native plants for your garden requires a bit of research. Here are some high-nectar plants that are particularly appealing to native butterflies.

Lavender (Lavandula)
Lavender is a classic choice for any garden, characterised by its fragrant purple flowers and hardy nature. Not only does it add a pop of colour to your garden, it’s also adored by a variety of butterflies, bees, and moths for its abundant nectar.
Marjoram (Origanum)
Marjoram, also known as oregano, is a herb that’s easy to grow and has a long flowering period, from spring through to late summer. Its small pinkish-purple flowers are a nectar source for many butterfly species.
Field Scabious (Knautia arvensis)
This plant bears beautiful blue-violet flowers that bloom from June to September, making it a nectar-rich dining spot for butterflies throughout the summer.
Designing a Butterfly-friendly Garden
Aside from choosing the right plants, the design of your garden can also greatly influence how attractive it is to butterflies. Butterflies love sunbathing, so ensure your garden has plenty of sunlit areas. A garden that provides ample shelter from wind, such as one with well-placed hedges or walls, is also more likely to attract these delicate creatures.
A variety of plants should be included to provide a rich source of nectar throughout the year. This ensures that butterflies have food in each stage of their lifecycle. Planting your flowers in clusters can also make them more appealing to butterflies, as they can feed without expending too much energy moving from plant to plant.
Adapting Your Gardening Practices
While introducing native plants is a significant step towards creating a butterfly-friendly garden, adopting wildlife-friendly gardening practices can further enhance the appeal of your garden for butterflies.
Avoid using pesticides as these can harm butterflies, bees, and other beneficial wildlife that visit your garden. Opt for organic methods to deal with pests. Also, a healthy soil is necessary for plants to thrive. Regularly enrich your soil with organic matter like compost or well-rotted manure.
In addition, providing water sources such as a bird bath or shallow dish can offer butterflies some much needed hydration during hot summer months. The combination of the right plants, garden design, and conscious gardening practices can create a garden where native butterfly populations can thrive.
As gardeners, you hold the power to create sanctuaries for these beautiful creatures. With thoughtful planning and planting, you can contribute to the conservation of native butterfly populations, while also enjoying the added beauty they bring to your garden.
Butterfly Host Plants: The Unsung Heroes
A critical component in attracting butterflies to your garden is introducing host plants. While nectar-rich flowers feed adult butterflies, host plants are essential for butterfly larvae, or caterpillars. Different butterfly species lay their eggs on specific host plants because these plants provide the necessary nutrients for their larvae to develop.
The Small Tortoiseshell and Red Admiral, both native to the UK, lay their eggs on the Stinging Nettle (Urtica dioica). This fast-growing, native plant is often perceived as a weed, but it’s actually crucial for these butterfly species.
Another valuable host plant is the Holly (Ilex aquifolium). The Holly Blue butterfly is known to lay its eggs on this evergreen shrub. Similarly, the Common Buckthorn (Rhamnus cathartica) is a desirable host plant for the Brimstone butterfly.
Remember, it’s not just about the adult butterflies; supporting the entire butterfly life cycle is what truly builds a sustainable butterfly garden.
Butterfly Bush: The Ultimate Nectar Source
The butterfly bush (Buddleia davidii), despite being native to China, has become naturalised in the United Kingdom. Its nectar-rich, fragrant flowers are an irresistible attraction for butterflies.
In bloom from early summer to autumn, its conical flower clusters come in a variety of colours – from deep purple to white. This ensures a continuous supply of nectar when many other plants are past their prime.
However, it’s important to note that while butterfly bush is a fantastic nectar source, it is not a host plant for any native UK butterfly species. Therefore, it should be integrated into your garden alongside native plants, not as a replacement.
Conclusion: Nurturing British Wildlife in Your Garden
Establishing a butterfly-friendly garden is a rewarding way to engage with the ecosystem and contribute to the conservation of British wildlife. Remember, the key to attracting butterflies is to plant a variety of native and nectar-rich plants that provide food and shelter throughout their entire life cycle.
Ensure your garden space offers full sun, well-drained soil, and wind protection. Be mindful of your gardening practices, favouring organic methods over harmful pesticides.
Creating a butterfly garden is not just about providing a habitat for butterflies and moths. It is also about immersing yourself in the beauty and intricacy of nature. As you watch butterflies, from the radiant Red Admiral to the dainty Small Tortoiseshell, fluttering around your garden, you’ll realise that your efforts are truly contributing to the preservation of these magnificent creatures.
Remember, every plant makes a difference, and each butterfly attracted to your garden is a testament to the positive impact you can have on the environment. Happy gardening!
