Planting Nectar-Rich Flowers for Bees and Butterflies

Why Open, Single Blooms Beat Fancy Doubles

If you only change one thing in your garden this year, make it this: stop buying double flowers. Those ruffled, petal-packed blooms may look lavish on the garden centre bench, but for bees and butterflies they are often a dead end. Years of breeding have turned stamens and nectaries into extra petals, leaving little or nothing to eat.

What pollinators need is an open, single flower with a visible centre — a landing pad plus a drink. Think of the flat daisy family, the lipped blooms of the mint family, and the bell-shaped flowers of foxgloves. You will often see this written as single, open, nectar-rich, and it is the single most useful phrase to carry around a nursery.

Native and near-native plants tend to score highest, but plenty of garden favourites earn their place too. The good news is that many of them are cheap, tough and generous with seed.

Best Choices for Pots, Balconies and Tiny Plots

Small-space growing is no barrier to a bee-friendly garden. A sunny balcony can outperform a large shaded lawn any day, because warmth and shelter matter as much as square footage. Aim for at least half a day of direct sun and shelter from strong wind.

• Lavender — 'Hidcote' or 'Munstead' for compact growth. Terracotta pot, gritty compost, sharp drainage, and resist the urge to feed or overwater. Trim lightly after flowering, never into old wood.
• Catmint — Nepeta 'Six Hills Giant' spills beautifully over a pot edge and buzzes with bees from May to September if you shear it back after the first flush.
• Marjoram and oregano — dual purpose herbs. Leave a few stems to flower and you will have clouds of tiny nectar-rich blooms in late summer.
• Calendula and borage — sow direct in a deep pot in April. Borage refills with nectar constantly, which is why you will find bees working it from dawn.
• Single dahlias — look for the open, daisy-like varieties rather than the dinner-plate doubles. They flower until the first frost.

Group pots together rather than scattering them. A cluster of five containers creates its own microclimate and gives passing pollinators a target they can find by scent from metres away.

Woodland and Shady Corners

Shade is not the enemy, but it does change the planting list. Dappled woodland light suits spring-flowering plants that complete their season before the canopy closes over — precisely when queen bumblebees are emerging and hungry.

• Foxgloves — Digitalis purpurea is the classic woodland spire. It self-seeds freely in leaf mould and its tubular flowers are built for long-tongued bumblebees. Let some flower spikes stand and scatter seed.
• Lungwort — Pulmonaria flowers in early spring in pink and blue on the same plant, a lifeline for emerging bees.
• Hellebores — single-flowered forms only; the doubles offer little. They bridge the gap between snowdrops and the first warm days.
• Wood anemone and native bluebell — buy bluebells from a reputable UK-grown source, never dug from the wild, and never the Spanish kind, which swamps our native species.
• Hardy geraniums — Geranium 'Rozanne' and G. phaeum cope with rooty shade and flower for months.

Improve the soil with leaf mould rather than rich compost, and avoid disturbing the leaf litter — that is where many solitary bees and moths overwinter.

Plant in Drifts, Not Dots

A single lavender in a sea of grass is hard work for a bee. Pollinators forage by sight and scent, and they navigate far more efficiently between clumps of the same plant. This is why planting in drifts — repeated groups of three, five or seven of one variety — works so well.

As a rough guide, aim for a patch at least 60cm by 60cm for a proper drift in a border. In a small garden, one generous pot of catmint counts as a drift in its own right. Repeat the same plant in two or three places around the plot, and you create a route rather than a single pit stop.

Plant for succession, too: something in flower in March, something in June, something in September. A garden that feeds insects for eight months is worth far more than one spectacular fortnight in July.

Leave the Seed Heads Standing

Resist the autumn tidy-up. Seed heads are winter food and shelter rolled into one.

• Teasels and echinacea hold seed that goldfinches strip through the cold months.
• Sedum — Hylotelephium 'Herbstfreude' — turns from pink nectar bar in September to bronze seed head that frosts beautifully and feeds on.
• Hollow stems from foxgloves, catmint and marjoram make winter bedrooms for solitary bees and lacewings.
• Leaf litter and fallen stems shelter butterflies, moths and ladybirds through the hardest weeks.

Cut back in late February or March, just as new growth stirs, and leave the cuttings in a loose heap at the back of the border for a fortnight before composting.

Small Habits That Make a Big Difference

Skip pesticides entirely — even the organic ones rarely distinguish between aphids and the larvae eating them. Leave a shallow dish of water with pebbles for drinking. Let a patch of lawn grow long and see what turns up. And when you deadhead, do it selectively: tidy the front of the border, but leave the back to seed.

Most of all, plant more than you think you need. A garden that feeds bees and butterflies generously will also feed your eyes, your birds and your curiosity — and it will look, quite simply, alive.
