Why a Border That Flowers All Year Matters

A bee-friendly border is not a one-off planting scheme, it is a long, slow conversation with the seasons. Solitary bees and bumblebees emerge at different times, and a colony's needs change from week to week. A queen bumblebee waking in March after a long winter needs an immediate source of nectar and pollen. By July, worker bees are gathering pollen by the sackful to feed growing larvae. Come September, new queens and next year's bumblebee queens need to build up fat reserves for hibernation.

If your border blazes for three weeks in June and then fizzles out, you are feeding bees only when food is already plentiful. The trick is to keep something in flower from early spring to late autumn, with overlapping peaks so there is never a lean fortnight.

The Building Blocks: Native and Long-Flowering Plants

Native plants deserve first place in a British bee border because our bees evolved alongside them. Their flowers are often simple and open, shaped for the tongues and body sizes of local species, and their nectar is rich and familiar. Non-native plants are by no means unwelcome, especially those with long flowering seasons, but a strong backbone of natives gives you reliability.

Aim for a mix of single, open flowers rather than double forms. Doubles may look generous, but many have lost the stamens and nectaries that make them worth a bee's visit. If you can see the centre of the flower, it is probably doing a job for pollinators.

Spring: Fuel for the First Bees

Early spring is the hungriest time of year for bees, because there is very little in flower and the weather is often raw. Your border should open the season gently but generously.

• Hellebores and pulmonaria (lungwort) flower in late winter and hold their blooms for weeks, feeding early bumblebee queens.
• Wallflowers add scent and colour in April, and their nectar is readily accessible.
• Native bluebells and wood anemones suit shadier parts of the border and provide spring pollen.
• Forget-me-nots self-seed freely and give a soft blue haze that early solitary bees adore.
• Flowering currant shrubs can be planted at the back of the border and hum with bees on a warm April afternoon.

Leave these plants to naturalise where possible. A border that shifts from hellebores to wallflowers to forget-me-nots gives bees a continuous spring larder rather than a single feast.

Summer: Keeping the Momentum Going

Summer is easy in the sense that bees are abundant, but hard because competition is fierce. The aim is to pick plants that flower for months rather than a fortnight, so your border is always the most rewarding stop on the bee's route.

• Catmint (Nepeta) flowers from June to September if cut back after the first flush, and is a magnet for bumblebees.
• Salvia, especially the deep blue and purple types, bridges mid and late summer with rich nectar.
• Purple loosestrife and marsh woundwort suit moist corners and flower for weeks.
• Scabious and field knautia bring a wild meadow feel and support hoverflies as well as bees.
• Foxgloves and hollyhocks give vertical drama and long-tongued bees a proper challenge.
• Thyme and marjoram are low-growing, drought-tolerant and flower repeatedly if deadheaded.

Deadheading is the quiet workhorse of a bee border. Cutting spent blooms back to a side shoot encourages another flush, and each flush means another few weeks of nectar through July and August.

Late Season: Feeding the Next Generation

Autumn is when new queens need to lay down fat, and when the last of the solitary bees are stocking their nest cells with pollen. This is where many gardens fall short, so plant for it deliberately.

• Asters, both the small-flowered Michaelmas daisies and the native sea aster, flower late and are worth their weight in gold.
• Sedum spectabile (ice plant) opens flat pink heads in September, packed with nectar. You can watch the bees crawl across the flowerheads like commuters on a platform.
• Japanese anemones will flower into October in a warm year and fill the gap before frost.
• Ivy is a superb autumn nectar source. It may clothe a wall or fence rather than sit in the border, but it deserves a spot nearby.
• Lavender and hyssop often rebloom lightly in milder autumns if you trim them after the main flush.

As autumn fades, resist the urge to tidy everything to the ground. Many bees overwinter in hollow stems, in leaf litter and in the fluffy seed heads that stand through winter. Leave the border a little shaggy until late spring.

Planting for Continuous Colour and Continuous Nectar

Design the border as a series of overlapping waves rather than a single block of colour. Group plants in threes or fives so their scent and pollen draw bees in from a distance, and repeat them down the border so there is always something within easy reach.

Watch your own border for a fortnight before you plant. Which weeks are empty? Slot in a long-flowering native or a repeat-flowering herb to fill that gap, and your garden becomes a reliable, year-round larder for the bees that visit it.
