How to attract butterflies – expert advice on making a butterfly garden

Attracting butterflies – and other pollinators – to your garden is a must. This is how to create a butterfly garden that's beautiful, too

Knowing how to attract butterflies to your yard has never been more important. There is no doubt that gardeners have an important role to play in supplementing nature by improving gardens so they are more supportive to valuable pollinators, including butterflies, bees, moths, wasps, hoverflies, beetles and many others. 

Butterflies, in particular, are considered a key indicator of a healthy environment with three-quarters in decline and four species extinct, it is clear there is much to be done. 

'A good pollinator garden needs to work a bit like a good supermarket – well stocked whenever you visit and with something for everyone,' says Helen Bostock, senior horticultural advisor at the RHS. 

'Anyone with a good range of flowering plants in their gardens is probably already doing pretty well at catering for pollinators, but we can make it even better by planning our planting scheme so there is something in flower in any given month,' she adds.

Cultivate a butterfly-friendly space with nectar-rich colorful flowers and wildlife garden ideas, and you will be able to enjoy spotting the likes of a Red Admiral, Peacock, Painted lady, Comma, Brimstone, Gatekeepper and Small Tortoiseshell butterflies dancing between the blooms. 

How to attract butterflies

Our gardens are important corridors between natural habitats; a diverse, nectar-rich café allows butterflies and other insects to flit from flower to flower, pollinating and enabling seeds and fruit production. 

Butterflies, once on the wing, cover large areas than bees and get almost all of their food from nectar. Pollen sticks to their bodies as they feed, so that they pass it from flower to flower, pollinating the plants, but unlike bees, they don't eat pollen.

Different pollinators require different shapes of flowers and some will only visits to feed on particular blooms and plants.

In general, however, single, open flowers, such as old-fashioned cottage garden plants, are best to give easy access, and ideally planted in drifts and placed in a sunny, sheltered spot.

Pollinators don't like double, multi-petalled and highly hybridized flowers as they may lack pollen and nectar and be difficult to access. 

'Years of selection for increasingly showy blooms has resulted in flowers losing their attraction to pollinators, but there are plenty of traditional, cottage garden plants which are tip-top as far as these insects are concerned,' explains plantswoman Sarah Raven.

Butterflies also like to stick their long tongue into tubular flowers and take nectar from a variety of colorful blooms, both native and non-native. Some of their favorites include:  

  • Red valerian
  • Buddleia
  • Honeysuckle
  • Verbena bonariensis
  • Lavender
  • Wallflower
  • Marjoram
  • Loosestrife
  • Echinacea
  • Cornflower
  • Hollyhock 
  • Knapweed.

'There are some flowers which are so deep that they are much more accessible to butterflies and moths with longer tongues, such as phlox and dianthus. It is a good idea to plant a range of plants with different shapes that flower through the year,' explains Anthony McCluskey, project officer from Butterfly Conservation

'Butterfly borders can provide lots of food for other types of insects, like bees and hoverflies, too, so they will go a long way to helping local populations of other pollinators,' he adds.

The colors preferred by butterflies can vary between the species, especially if they also lay their eggs on the flowers. 'Overall, though, there is no strong preference for flowers of any particular color, so any and all garden color schemes are useful for them,' adds Anthony. 

His top five plant choices include: 

  • Heather for the first butterflies in early spring; 
  • Nasturtium to feed caterpillars of white butterflies; 
  • Eupatorium for late summer; 
  • Thyme for pots and window boxes;
  • Fruit trees with flowers for the butterflies;
  • Leaves for moth caterpillars. 

'Which flowers are the best for pollinators is an area of intense research, and it is important to take all lists with a pinch of salt as they are so selective, and can give the wrong impression that there are only a few good plants when in fact there are many,' says Sarah Raven. 'As a general rule, it is the blue, mauve and purple spectrum of plants, which are richest for nectar.'

'Scent is more important for moths which fly in the evening and night; certain flowers become more heavily scented at these times – such as honeysuckle, night- scented phlox, evening primrose and jasmine. Planting these will help feed insects working the night shift,' says Anthony. 

What can you put out to attract butterflies?

Although summer sees the highest number of insect pollinators, they are around through most of the year, so need reliable food sources each season. 

In winter: 'Butterflies and bees hibernate in winter, so don't need to forage when it is truly cold, but it is good to think of having a food source in your garden from March to November and at least a few winter-flowering plants that can be used by bees on some warmer, sunny days in spring and autumn,' explains Sarah Raven.

Sarah's choices from November to February include chaenomeles, Clematis cirrhosa, eranthis, or winter aconites, Lonicera x purpusii, winter-flowering mahonias, such as 'Charity', and Viburnum tinud.

In spring: Adding spring choices, such as primrose, bugle and forget-me-nots extends the supply of nectar. 

In March, Sarah counsels to include crocus, Erica carnea, primrose and polyanthus, pulmonaria, rosemary, single snowdrops, violets and willow.

In autumn: Autumn options of aster, scabious and verbena, also extend the supply of nectar so valuable for providing butterflies with the energy to fly and mate. 

Year round: Some perfect choices for a range of pollinators throughout the year include ornamental and fruit tree blossoms, primulas, violents, muscari, chives, geraniums, achillea, umbels, nepeta, salvias, Japanese anemones, autumn crocusesm rudbeckias, dahlias, hellebores and sarcococca. 

Lavenders, particularly Lavandula x intermedia, attract a wide range of insects and, compared with borage, lots of butterflies and hoverflies as well as relatively more bumblebees to honeybees, advises Sarah.  

'Flowering shrubs and trees are incredible pollen and nectar providers. Ivy, too, if given the chance to mature and flower, is a tremendous late source of nectar and pollen, supporting a huge range of flies, bees, wasps and other insects,' says Helen Bostock from the RHS

How do I attract butterflies?

The best way to attract and keep butterflies coming back, other than planting things butterflies love is to avoid using pesticides or herbicides, especially on flowers, as they can kill pollinators and also enter the food chain. Rewilding and organic gardening without chemicals will help all butterflies and other insects in your garden, and also promote an increase in beneficial insects. 

Think of the needs of butterflies and other pollinators through the different stages of their life and provide food, water and sheltered habitats:

  • Let some areas of your garden be untidy – long grass, leaf piles and plant debris are more important hibernation habitats for many butterflies and moths;
  • Do not mow areas of grass, or cut the lawn less often – dandelions and clover are a great source of nectar;
  • Leave some weeds – many native weeds have evolved to fit with the breeding and feeding of native pollinators, giving shelter and safe nesting sites to lay their eggs;
  • Make a stumpery or a bee or bug hotel in a quite corner of the garden;
  • Give some thought to supplying larval food, often wild plants, as some pollinators need host plants to develop to adult stage, such as a patch of nettles for many varieties of moths and butterflies may not breed in our gardens, as we can't replicate the specific conditions in the wild, but our gardens are crucial to complement their native habitats and help maintain pollinator numbers.

What do you put in a butterfly feeder?

The best things to put in butterfly feeders are probably things you already have at home. To start: if your butterfly feeder is in a color that attracts butterflies you will have a better chance that they will visit, so think pink, purple or blue – or other bright colors that mimic native flowers. 

What to feed butterflies with? Butterflies love nectar, but in place of that, put out overripe, mashed fruit, such as bananas, pears, oranges, melons, plums, berries and pineapple. Add water to the mashed fruits to make them easier for the butterflies, or put out clean, fresh water daily in a shallow dish with pebbles in so that butterflies can drink safely.
