Plants to attract pollinators: purple and pink

Choosing plants that attract pollinating bees and butterflies is a fundamental part of sustainable gardening. Improving the range of creatures visiting our gardens is good for biodiversity and fascinating to watch

Quick facts

  • Having a variety of flower types can attract more pollinators
  • Choosing plants that flower at different times of the year provides more opportunity for pollinators
  • Many insects are attracted to blue and purple colours

The planting plan

James Lawrence, RHS Principal Horticultural Advisor, has designed this simple, attractive, and most importantly, sustainable border design that you can try this at home with purple- and pink-flowered plants that are easy to grow, widely available and look good together.

Purple and pink flowers to attract pollinators

Choosing plants to attract pollinators

Pollinating insects are in decline, but there are plenty of flowering plants to help them. Increasing flowering plants in our gardens can also improve fruit and vegetables: with more pollinating insects around, harvests will be bigger and better.

The Nepeta provides some ground cover and will help prevent erosion of bare soil. Ground cover plants can also help to reduce moisture evaporation from the soil surface and suppress weed growth.

Until the plants have filled out, an organic mulch, preferably homemade compost, can help to improve soil moisture retention and weed suppression. Mulches should be spread when the soil is already moist to help trap some of that moisture before it dries out in summer. Avoid spreading bagged potting compost on beds and borders.

1 - Weigela florida ‘Alexandra’
2 - Buddleja davidii 'Nanho Purple'
3 -  Allium ‘Gladiator’ 
4 - Verbena bonariensis
5 - Nepeta racemosa ‘Walker’s Low’
1 - Weigela florida ‘Alexandra’ is a deciduous shrub with dark purple to almost black foliage, with a profusion of pink, open trumpet-shaped flowers in early summer.

2 - Buddleja davidii 'Nanho Purple' is a semi-evergreen shrub with grey-green leaves. It has sweet-smelling, long, cone-shaped heads of small violet-purple flowers with orange centres all summer into autumn. These are a magnet for butterflies.

3 - Allium ‘Gladiator’ is a perennial bulb with long, strap-shaped grey-green leaves, which die back at flowering time. Dense, rounded clusters of purple flowers are borne on tall stems in early summer.

4 - Verbena bonariensis is a herbaceous perennial with branched clusters of bright violet-purple flowers held atop tall stems with sparse, green leaves, from summer into autumn.

5 - Nepeta racemosa ‘Walker’s Low’ is a deciduous sub-shrub with silver-green aromatic leaves. The flowers are lilac-blue on dark stems. This catmint comes into flower in early summer and will continue into autumn if deadheaded.

About plants for pollinators

Using scientific evidence, our extensive experience and the records of gardeners and beekeepers, we’ve selected a range of year-round flowering Plants for Pollinators to tackle the decline in pollinator numbers. Visit our Plants for Pollinators page to discover more of the best plants for attracting pollinators.
 

Growing plants for pollinators

Many insects are suffering from a lack of pollinator-friendly plants in the countryside to provide nectar and pollen. By offering a good range of pollinator friendly plants in our gardens, we can help these essential creatures to thrive. Increasing biodiversity is also benefical for encouraging a healthy garden ecosystem in general.

Choose plants with a variety of different flower types and structures in order to attract a wider range of pollinators across the seasons. A succession of overlapping flowering times ensures there is always something available.

Why choose a sustainable planting combination?

Using the ethos of ‘right plant, right place’ to create a sustainable planting combination is great for the environment. It helps to avoid waste and the use of products and practices needed to try and help ailing plants, such as applying fertiliser. It also creates robust, long-lived planting that benefits soil health and garden biodiversity. For more information about sustainable gardening, please see the RHS Sustainability Strategy.

Additionally, this combination will also attract more pollinating insects into the garden, creating better diversity by in turn encouraging birds and other wildlife into the garden.
