Why Choose RHS Plants for Pollinators?
Choosing plants that are recognised by the Royal Horticultural Society (RHS) for their pollinator benefits ensures you are selecting species proven to support bees, butterflies, hoverflies, and other beneficial insects. These plants are not only attractive additions to any garden but also provide crucial food sources and habitat. By focusing on RHS-endorsed varieties, you can create a vibrant, biodiverse ecosystem that aids in pollination, which is fundamental to our food supply and the health of the wider environment.
The RHS's work involves extensive research and trials to identify plants that offer the most sustenance and appeal to a wide range of pollinators. This means when you opt for RHS plants for pollinators, you are investing in species that have been evaluated for their nectar and pollen content, flowering period, and overall accessibility to insects. This approach takes the guesswork out of creating a wildlife-friendly garden, offering a reliable foundation for attracting and sustaining these invaluable creatures.
A garden rich in pollinator-friendly plants can significantly boost local biodiversity. It transforms a simple outdoor space into a dynamic habitat, offering a lifeline to insect populations that are under increasing pressure from habitat loss and environmental changes. Furthermore, these plants often require less intensive care than many ornamental varieties, thriving in conditions that mimic their native environments, making them a robust choice for gardeners of all skill levels.
- RHS-recognised plants provide proven support for bees and butterflies.

Key Plant Types Recommended by the RHS
The RHS categorises a vast array of plants that benefit pollinators, ranging from hardy perennials and shrubs to annuals and bulbs. Understanding these categories can help you plan a garden that offers continuous support from spring through to autumn. The key is to select plants with different flowering times to ensure a consistent food supply.
Perennials for Continuous Bloom
Perennial plants are the backbone of a pollinator garden, returning year after year and often becoming more established and productive over time. Many RHS-endorsed perennials offer long flowering periods, providing a steady source of nectar and pollen.
Echinacea (Coneflower) species are highly regarded. Their large, open flower heads are perfect for bees and butterflies to land on, and they typically bloom from mid-summer into autumn. Varieties like Echinacea purpurea are particularly popular. Another excellent choice is Salvia, commonly known as Sage. Many salvias, especially those with spikes of tubular flowers like Salvia nemorosa, are magnets for bees. They bloom for extended periods, often from early summer until the first frosts, and come in a range of colours from deep purple to pink and white.
Herbs are also exceptionally beneficial. Lavender (Lavandula) is a classic, its fragrance and purple spikes irresistible to bees. Mint (Mentha) varieties, when allowed to flower, provide abundant nectar. Bee balm (Monarda) is another star, with its distinctive, often brightly coloured flowers that attract a wide array of pollinators.
Shrubs and Trees for Structure and Early/Late Food
Incorporating shrubs and trees provides essential structure to your garden and can offer vital early-season or late-season nectar and pollen when other plants may not be in bloom.
For early spring nectar, Hawthorn (Crataegus) and Blackthorn (Prunus spinosa) are excellent native choices. Their masses of white flowers provide a crucial early food source. Later in the season, buddleja, often called the 'butterfly bush', is an RHS favourite for its long, vibrant flower spikes that attract a multitude of butterflies and bees. Ensure you select sterile or less invasive cultivars where appropriate.
Consider **Viburnum** species; many offer fragrant flowers in late winter or early spring. For late-season interest and food, **Hebe** varieties can provide blooms well into autumn, and **Ivy** (Hedera helix), often overlooked, is a vital late-season nectar source for many insects preparing for hibernation.
Annuals and Bulbs for Seasonal Surprises
Annuals and bulbs can fill gaps, provide seasonal colour, and offer specific bursts of food for pollinators.
Sunflowers (Helianthus annuus) are iconic for attracting bees, offering both pollen and nectar. Cosmos and Calendula are also good choices for summer colour and pollinator attraction. For bulbs, **Crocus** and **Snowdrops** are invaluable for very early pollinators, while **Alliums** provide striking spherical flower heads that are particularly attractive to bees in late spring and early summer. Ensure you select single-flowered varieties where possible, as double flowers can sometimes be less accessible or lack nectar/pollen.
The true value of a plant for pollinators lies in its accessibility and nutritional content, not just its decorative appeal.
When selecting plants, aim for a variety of flower shapes and colours. Bees, for instance, are attracted to blue, purple, yellow, and white flowers, while butterflies often prefer warmer colours like red, orange, and pink. Tubular flowers are excellent for long-tongued bees and butterflies, whereas open, flat-topped flowers are ideal for shorter-tongued bees and hoverflies.
Creating a Pollinator-Friendly Habitat
Beyond selecting the right RHS plants for pollinators, creating an environment that actively encourages and sustains them involves several considerations. It’s about providing more than just food; it’s about offering shelter, water, and a safe space for these vital creatures to thrive.
Provide Diverse Food Sources
As discussed, a succession of blooms is paramount. Plan your planting so that something is always in flower, from the earliest spring bulbs to the last autumn blossoms. This continuous buffet is essential for sustaining different pollinator species throughout their active periods. Mixing native plants with well-loved garden varieties often yields the best results, catering to local insect populations while also providing general appeal.
Consider plants that offer both nectar and pollen. Bees, for example, collect pollen to feed their young. Flowers with accessible pollen, such as poppies and sunflowers, are just as important as nectar-rich blooms. The RHS also highlights plants that have a high nectar score, indicating their rich sugar content, which provides energy for flying insects.
Offer Shelter and Nesting Sites
Many pollinators, especially solitary bees, need places to nest. Leaving some areas of your garden a little 'wild' can be incredibly beneficial. This might include:
- Bare patches of soil: Many solitary bees nest in the ground.
- Hollow stems: Dead stems from perennials like raspberries or brambles can provide nesting tubes.
- Log piles or rockeries: These offer shelter for a variety of insects, including hibernating butterflies.
- A bug hotel: These structures can provide pre-drilled holes and natural materials for nesting solitary bees.
Avoid over-tidying, especially in autumn. Leaf litter and decaying plant material provide essential overwintering habitats for many insects. For hedgehogs, which can also benefit from a wilder garden, consider leaving out water or food, but be mindful of what is appropriate – feeding station for hedgehogs should be specific to their needs; can I feed hedgehogs mealworms or do hedgehogs eat fruit are common questions, but it's best to check expert advice to avoid harm. Hedgehogs are not typically insectivores in the way bees are, but a healthy insect population in your garden supports the entire food web.
Water Sources
Pollinators, like all living creatures, need water. A shallow dish filled with pebbles or marbles, with water just covering the top, provides a safe drinking spot. The pebbles give insects a place to land and drink without drowning. A simple bird bath with shallow edges or a pond can also serve this purpose.
Avoid Pesticides
Perhaps the most critical step is to eliminate the use of pesticides. Even products marketed as 'bee-friendly' can still harm beneficial insects. Opt for organic pest control methods or learn to tolerate minor pest damage. A healthy garden ecosystem with plenty of pollinators will naturally help keep pest populations in check.
Consider Native Plants
While many non-native plants are excellent for pollinators, native plants are often perfectly adapted to local insect species and can provide a more robust, sustainable food source. Identifying wildflowers uk that are suitable for your garden can be an excellent way to boost local biodiversity.
When planning, think about the lifecycle of your target pollinators. For example, butterflies need host plants for their caterpillars as well as nectar sources for adults. Researching specific species you wish to attract can inform your plant choices beyond general pollinator support.
Comparing Top RHS Plants for Pollinators
When selecting from the vast list of RHS plants for pollinators, it's helpful to compare their strengths based on factors like flowering period, attractiveness to specific insects, and ease of care. This comparison helps tailor your garden to specific needs and conditions.
| Plant Type | Key Pollinators Attracted | Flowering Period | Ease of Care | Notes |
|---|---|---|---|---|
| Lavender (Lavandula) | Bees (especially bumblebees), butterflies | Summer (June-August) | Easy | Drought tolerant once established, prefers well-drained soil. |
| Echinacea (Coneflower) | Bees, butterflies, hoverflies | Mid-summer to Autumn | Moderate | Prefers full sun; deadheading can prolong flowering. |
| Salvia (Sage) | Bees (bumblebees, honeybees), butterflies | Early Summer to Autumn | Easy | Many varieties, some hardier than others. Good for dry conditions. |
| Buddleja (Butterfly Bush) | Butterflies, bees | Summer to Autumn | Easy | Can grow large; prune hard in spring. Attracts many species. |
| Alliums (Ornamental Onion) | Bees (especially bumblebees) | Late Spring to Early Summer | Easy | Plant bulbs in autumn. Striking globe-shaped flowers. |
| Borage (Borago officinalis) | Bees (especially honeybees) | Summer | Easy (self-seeds readily) | Annual, edible flowers and leaves. Great for bees. |
When choosing, consider your garden's conditions: soil type, sunlight exposure, and available space. A plant that thrives in one garden might struggle in another. For instance, lavender requires excellent drainage and full sun, whereas borage can tolerate partial shade and will happily self-seed in many spots. Similarly, if you have a smaller garden, choosing compact varieties of shrubs or focusing on herbaceous perennials might be more practical than planting a large buddleja.
The number of pollinators in the UK is a significant concern, with various species facing decline. Creating a haven with RHS plants for pollinators is a tangible way to contribute to conservation efforts. Even a small balcony or patio can be transformed with a few well-chosen pots, providing essential resources for our local insect populations. Remember, every little bit helps in supporting the intricate web of life that depends on these hardworking insects.
Ultimately, the goal is to create a resilient, dynamic garden that not only looks beautiful but also actively supports the natural world. By following the RHS's guidance and considering the needs of pollinators, you can cultivate a space that buzzes with life and contributes positively to the environment.
