The best pollinator-friendly plants for urban outdoor spaces are lavender, salvia, catmint, borage, thyme, coneflower, sedum and alliums, with phacelia, nasturtium and sweet alyssum for quick summer colour. Most grow happily in pots on a balcony, patio or windowsill. Choose single, open flowers, plan for something in bloom from early spring to late autumn, skip pesticides, and even a few containers will feed bees, butterflies and hoverflies.
This guide covers the planting principles that matter most, the best plants for containers, a seasonal bloom plan, and how to set up a pollinator garden on a balcony or small patio.

Why Urban Pollinator Gardens Matter
Bees, butterflies, moths and hoverflies have lost much of their habitat to farming, development and pesticide use. City gardens, balconies, parks and verges together form a patchwork of food that can help fill that gap. A pot of lavender on a high balcony is not isolated; it is one stop on a route that insects use across a whole neighbourhood.
The RHS Plants for Pollinators list, expanded in 2025 to more than 10,000 plants, is based on published evidence of which plants UK pollinators actually visit. It is a useful check before you buy. For the bigger picture of wildlife gardening, see our guide on designing a wildlife-friendly garden.
How to Choose Pollinator-Friendly Plants
Choose Single, Open Flowers
Many double-flowered varieties have extra petals in place of the parts that make pollen and nectar, or so many petals that insects cannot reach the centre. Choose single, open flowers where you can see the middle, such as single dahlias rather than pompom types.
Mix Native and Garden Plants
Native wildflowers support many local insects, including some specialist bees, so include a few. In the UK, foxglove, wild marjoram, knapweed, field scabious and red clover are good choices. The RHS list shows that well-chosen non-native garden plants, such as salvia and lavender, are also valuable, especially for extending the flowering season. Our guide to native plants explains how to find species for your area.
Plan for Flowers From Early Spring to Late Autumn
Queen bumblebees emerge hungry in early spring, and many insects need food well into autumn. Aim for something flowering in every period, not just midsummer. The RHS notes that flowers between September and April are especially valuable because there is less forage around.
Avoid Pesticides
Insecticides, including some labelled organic, can kill or harm pollinators that visit treated plants. Deal with pests by hand-picking, rinsing aphids off with water, and encouraging predators such as hoverflies and ladybirds. Our guide on keeping pests away from outdoor plants covers safe methods.
Add Water
A shallow saucer of water with pebbles or marbles gives bees somewhere safe to land and drink in hot weather. Change the water every two or three days to keep it clean and stop mosquitoes breeding.
Best Pollinator-Friendly Plants for Urban Spaces
Lavender
Among all pollinator-friendly plants, English lavender (Lavandula angustifolia) is one of the best for bees for sunny containers and window boxes, flowering for weeks in midsummer. It needs full sun and gritty, free-draining compost. Trim after flowering to keep it compact.
Salvia
Perennial salvias such as Salvia nemorosa produce spikes of blue, purple or pink flowers from late spring and often flower again if cut back. Bumblebees love them, and they cope well with dry pots once established.
Catmint
Catmint (Nepeta × faassenii) is one of the longest-flowering pollinator plants. Its soft blue spikes appear from late spring and rebloom after a trim. It is tough, drought-tolerant and suits large pots and edges in sun or light shade.
Borage
Borage’s blue, star-shaped flowers refill with nectar quickly, so bees visit them again and again. It is a fast, easy annual from seed that self-seeds freely, and the flowers are edible.
Thyme
Thyme is a compact herb whose small flowers attract many small solitary bees. Let it flower before cutting it back by about a third. It suits window boxes and the edges of sunny pots.
Coneflower
Coneflower (Echinacea purpurea) has large, open flowers that draw bees and butterflies from midsummer into early autumn. Leave the seed heads over winter for birds.
Bee Balm
Bee balm (Monarda) produces shaggy flower heads in red, pink and purple that bumblebees and butterflies visit through summer. It prefers moist compost and good airflow, as it can get powdery mildew.
Phacelia
Phacelia (Phacelia tanacetifolia) is so rich in pollen and nectar that farmers sow it as bee forage. It flowers within about two months of sowing; sow a pot every few weeks from spring to early summer for a long display.
Sweet Alyssum
Sweet alyssum forms low clouds of tiny, honey-scented flowers that spill over pot and basket edges. It attracts small bees and hoverflies, whose larvae eat aphids.
Nasturtium
Nasturtiums grow fast from seed, trail from baskets and pot edges, and flower all summer in orange, red and yellow. Bumblebees visit the flowers, and the leaves and flowers are edible.
Marigolds
Pot marigold (Calendula officinalis) and single-flowered French marigolds (Tagetes patula) are easy annuals that flower from early summer to the first frosts if deadheaded. Their open centres attract hoverflies and bees.
Alliums
Ornamental onions such as Allium ‘Purple Sensation’ and the drumstick allium (A. sphaerocephalon) grow from autumn-planted bulbs and give bees a big nectar source in late spring and early summer.
Foxglove
Foxgloves (Digitalis purpurea) are one of the best pollinator plants for shade; bumblebees climb right inside the tubular flowers. They are biennial, flowering in their second year, and self-seed. All parts are poisonous, so keep them away from children and pets.
Sedum (Stonecrop)
Stonecrop (Hylotelephium, formerly Sedum) flowers from late summer into autumn, when food is getting scarce. The RHS lists stonecrops among its top plants for autumn pollinators. It is drought-tolerant and ideal for pots.
Seasonal Pollinator Planting Plan
Mix pollinator-friendly plants so something is always in flower:
| Season | Plants to grow | Pollinators helped |
|---|---|---|
| Early spring (Mar–Apr) | Crocuses, pulmonaria, hellebores | Queen bumblebees, early solitary bees |
| Late spring (May) | Alliums, catmint, salvia, phacelia | Bumblebees, honeybees, solitary bees |
| Early summer (Jun) | Lavender, borage, nasturtium, foxglove | Bees, butterflies, hoverflies |
| Midsummer (Jul–Aug) | Coneflower, bee balm, calendula, sweet alyssum | Butterflies, bumblebees, hoverflies |
| Late summer (Aug–Sep) | Sedum, thyme, salvia, single dahlias | Late bumblebees, butterflies |
| Autumn (Sep–Oct) | Sedum, asters, ivy flowers, single dahlias | Ivy bees, late bumblebees, hoverflies |
Flowering ivy is one of the last big food sources of the year. The RHS notes that the ivy bee (Colletes hederae) times its emergence to ivy’s autumn flowering. Our garden calendar helps plan planting through the year.
How to Make a Pollinator Garden on a Balcony or Patio
Pollinator-friendly plants work best on a balcony when you follow a few simple rules.
- Group containers: Five or six pots of different pollinator plants together are far more useful than single pots scattered around.
- Use big pots: Perennials like catmint, coneflower and sedum need containers at least 30cm wide. Bigger pots also dry out more slowly.
- Go vertical: Railing planters, wall pots and hanging baskets of nasturtium, sweet alyssum or thyme add flowers without using floor space.
- Use peat-free compost and drainage holes: Mediterranean herbs like lavender and thyme need extra grit.
- Add water: Put a pebble-filled saucer of water among the pots.
Windy balconies dry pots quickly, so check watering often. Our guides to plants for small outdoor spaces and year-round balcony plants have more ideas.
Supporting Pollinators Beyond Bees
- Hoverflies: Visit open, daisy-like flowers and umbellifers such as fennel and dill. Their larvae eat aphids.
- Butterflies: Prefer flat flower heads to land on, such as sedum, Verbena bonariensis and single dahlias. Many also need caterpillar food plants, such as nettles for peacock and red admiral butterflies.
- Moths: Visit pale, scented flowers at night, such as night-scented stock, evening primrose and nicotiana. Our moon garden guide covers night-flowering plants.
- Solitary bees: The most varied group. Lavender, borage, phacelia, catmint and native wildflowers support many species.
Frequently Asked Questions
What are the best pollinator-friendly plants for small spaces?
Lavender, salvia, catmint, borage, thyme, sweet alyssum, nasturtium, sedum and alliums all grow well in containers and attract a wide range of pollinators.
Can I attract pollinators to a balcony or rooftop?
Yes. Grow a group of single-flowered, nectar-rich plants that bloom at different times, add a shallow dish of water and avoid pesticides. Even a few pots get regular visits.
Which plants attract bees the most?
Lavender, borage, phacelia, catmint, salvia, thyme, alliums and coneflower are among the most popular with bees. Choose single, open flowers rather than doubles.
What pollinator plants grow in shade?
Foxglove, pulmonaria, hellebores, astrantia and flowering ivy all provide food for pollinators in shadier spots. Our shade-loving outdoor plants guide has more options.
Do I need native plants for a pollinator garden?
Including some native plants helps local insects, but the RHS list shows many garden plants from elsewhere are also valuable. A mix that flowers from early spring to late autumn works best.
Final Thoughts
Pollinator-friendly plants turn even a small balcony into a useful stop for bees, butterflies and hoverflies. Start with three or four pots that flower at different times, choose single flowers, add water and skip the sprays. Then watch who visits and add more from there.
