A garden can look full of flowers and still offer very little to a colony of bees. The useful question is not simply what blooms, but what provides accessible nectar and pollen, when it flowers, and whether there is enough of it to make a worthwhile forage patch. The best pollinator plants for bees create a succession of food from the first mild days of spring until autumn, rather than one impressive but short-lived display.
For honey bees, planting matters most where forage is scarce or broken up by large areas of lawn, hard landscaping or intensive crops. For bumblebees and solitary bees, flower shape, open access to pollen and suitable nesting habitat are equally relevant. A good bee garden therefore needs variety, but it also needs repetition: a generous clump of one excellent plant is usually more useful than a single specimen of ten different varieties.
What makes a plant valuable to bees?
Nectar provides carbohydrates for energy. Pollen supplies protein, fats, vitamins and minerals needed to rear brood. Different plants offer these resources in different amounts, so a mixed planting is more reliable than relying on one fashionable ‘bee-friendly’ flower.
Flowering period is crucial in the UK. Colonies build rapidly in spring, often need support during the June gap when some major blooms finish, and must collect enough stores and pollen to raise healthy winter bees in late summer and early autumn. Weather can interrupt any nectar flow, so overlapping flowering times give bees options.
Where possible, choose single, open flowers rather than heavily double forms. Double blooms may look showy, but their petals can replace the pollen-bearing parts of the flower or make nectar difficult to reach. Native plants are often excellent choices, though well-selected non-native garden plants can also provide substantial forage. The aim is not purity, but dependable food.
The best pollinator plants for bees by season
Early spring: willow, fruit blossom and lungwort
Early spring is one of the most demanding periods for colonies. Queen bees of bumblebees are emerging, honey bee colonies are beginning to expand, and warm flying days can be limited.
Willow is among the finest early resources available. Goat willow and other suitable willows provide abundant pollen and nectar, and their catkins can be alive with insects on a sunny March day. It is best suited to a larger garden, damp ground, a boundary or a managed hedge, as some willows become sizeable trees.
Apple, pear, plum and cherry blossom offer valuable forage in April and May. A productive orchard is particularly useful because it combines many flowers in one place. Even a single fruit tree is worthwhile in a small garden, provided it is appropriate for the available space and pollination requirements.
Lungwort, or pulmonaria, is a practical choice for shaded borders. Its early flowers are especially popular with long-tongued bumblebees. Primroses, hellebores and flowering currant can also extend the spring offering, but avoid treating flowers or nearby weeds with insecticides while plants are in bloom.
Late spring and early summer: comfrey, alliums and foxgloves
Comfrey is hard to beat for a working bee garden. It flowers for a long period, regrows after cutting and attracts bumblebees in particular. Common comfrey can spread enthusiastically, so many gardeners prefer sterile Russian comfrey cultivars where control is needed. Give it room at the back of a border or in a less formal area.
Alliums are useful because their rounded flower heads carry many small flowers together, allowing bees to work efficiently. Choose varieties with open, nectar-rich blooms and staggered flowering dates. They fit easily into ornamental beds and are a good way to add bee forage without sacrificing a tidy garden design.
Foxgloves provide tall spires of tubular flowers in early summer and suit woodland edges, shaded areas and informal borders. They are biennial or short-lived perennials, so let a few plants set seed if you would like them to return. Take care around children and pets, as all parts are toxic if eaten.
Other strong choices for this period include hardy geraniums, salvias and catmint. Catmint is particularly useful in sunny borders, flowering generously and often continuing after a light trim.
Summer: lavender, borage and open daisy flowers
Summer is often when gardeners see the most bee activity, but not every summer flower is equally productive. Lavender earns its place in sunny, free-draining sites because it produces reliably and can be planted in quantity. English lavender is generally hardy and manageable, while lavandin varieties can make larger, later-flowering plants. Do not expect lavender to thrive in wet, heavy soil without improving drainage.
Borage is one of the most generous annual plants for bees. Its blue, star-shaped flowers replenish nectar quickly and may flower for months. It self-seeds readily, which is welcome in a wildlife patch but less so in a tightly controlled border. Sow a small area each year and let the plants fill gaps where appropriate.
Open-centred daisy flowers such as oxeye daisy, coreopsis and echinacea provide landing platforms and accessible pollen. Echinacea is particularly useful later in summer, though it needs a warm, reasonably sunny position to perform well. Leave the seedheads into autumn where possible: they are attractive and can feed birds.
Herbs are often overlooked. Oregano, thyme, chives, sage and rosemary can all support bees when allowed to flower. Oregano is especially effective, producing broad, busy patches of flowers in July and August. A herb bed can be both productive for the kitchen and genuinely useful for pollinators.
Late summer and autumn: sedum, asters and ivy
Late forage can make a real difference, particularly in urban and suburban gardens where autumn resources are limited. Hylotelephium, often still sold as sedum, produces broad clusters of tiny starry flowers that attract honey bees, bumblebees and hoverflies. It is drought-tolerant once established and works well in sunny borders.
Michaelmas daisies, now commonly sold as asters, extend colour and forage into September and October. Choose mildew-resistant varieties and divide congested clumps every few years. They can become tall, so shorter cultivars are often easier in an exposed garden.
Ivy deserves a special mention. Its late flowers are a major nectar source in September and October, followed by berries for birds. Mature ivy on a wall, fence or tree can support an extraordinary number of insects. It does need sensible management, but removing every strand from a garden can mean losing one of the last substantial forage sources of the year.
Plant for patches, not token flowers
A single lavender plant by the front door is better than none, but it will not transform the forage available to bees. Aim to plant in drifts or blocks, especially with smaller flowers. Bees tend to work efficiently when they can move from bloom to bloom without spending energy searching.
This does not mean every border needs to look like a wildflower meadow. Formal gardens can support pollinators through repeated planting of lavender, alliums, salvias, catmint and sedum. Cottage gardens may lean towards comfrey, foxgloves, herbs and asters. A wilder corner can include native hedgerow plants, knapweed, teasel and self-seeding borage. The best approach depends on soil, light, available space and how much maintenance you realistically want to do.
If you keep bees, avoid assuming your garden must feed the whole apiary. Honey bees forage over a large area, often several kilometres when necessary. Garden planting strengthens the local patchwork of food, provides a welcome resource during lean moments and helps many other pollinators that do not travel as far. It is part of good husbandry and good neighbourhood planting, not a replacement for assessing wider forage around an apiary.
A few planting choices to avoid
Be cautious with plants labelled ‘pollinator-friendly’ without further detail. The label is not a guarantee of accessible nectar or pollen. Inspect the flower: can you see an open centre, or is it packed with petals? Ask when it flowers and whether it has been treated with systemic pesticides before sale.
Wildflower seed mixes also vary widely. Some contain short-lived annuals selected for colourful photographs rather than long-term value. A perennial meadow mix suited to your soil may establish more slowly, but it can offer a more lasting habitat. Wildflowers need low fertility and careful cutting regimes, so they are not simply lawn seed scattered on rich ground.
Finally, do not tidy every corner too thoroughly. Hollow stems, leaf litter, tussocky grass and small patches of bare soil provide nesting or overwintering places for many solitary bees. Flowers are the food cupboard; habitat is the home.
Start with two or three gaps in your flowering calendar, then add plants in meaningful groups. A willow or fruit tree for spring, a patch of herbs and lavender for summer, and sedum or ivy for autumn can give bees far more than a garden that peaks for only a few weeks.
