Plants to attract pollinators: blue and purple

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

  • Choose plants that flower for long periods over spring and summer
  • Shades of blue are attractive to a variety of insects
  • Choose a wide range of flower shapes to encourage a wide range of insects

The planting plan

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

Blue and purple plants for pollinators

Choosing plants for 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 can be bigger and better.

The oregano provides some groundcover and will help prevent erosion of bare soil. Groundcover can also help to reduce soil surface moisture evaporation and suppress weed growth. Additional organic mulching can further improve soil moisture retention and weed suppression.


1 - Veronica x andersonii
2 - Callicarpa bodinieri var. giraldii ‘Profusion’
3 - Phlox paniculata ‘Blue Paradise’
4 - Echinops ritro ‘Veitch’s Blue’
5 -   Lavandula × intermedia Heavenly Scent
6 - Origanum vulgare ‘Compactum’
1 - Veronica x andersonii  provides some evergreen structure with long, dark leaves and spikes of blue to purple flowers in summer. 

2 - Callicarpa bodinieri var. giraldii ‘Profusion’ has excellent autumn interest as the foliage takes on pink tints and the bright purple berries display in clusters, which often persist into winter. 

3 - Phlox paniculata ‘Blue Paradise’ is a herbaceous perennial with tall leafy stems holding rounded heads of fragrant, dark-eyed, light to violet-blue flowers in early summer.

4 - Echinops ritro ‘Veitch’s Blue’ provides spherical, spiky blue flowerheads, which if left, provide good winter structure. The leaves are silver-green.

5 - Lavandula x intermedia Heavenly Scent provides scented purple summer flowers above grey-green aromatic foliage, giving some structure at the front of the border. 

6 - Origanum vulgare ‘Compactum’ has small, aromatic leaves and loose sprays of tiny pale pink to purple flowers from summer to early autumn.

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.

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.
