Why native flowers earn their place

If you want a garden that hums from spring to early autumn, native and near-native flowers are the most reliable starting point. Our bees, bumblebees, hoverflies and butterflies evolved alongside these plants, so they recognise the shapes, colours and scent signals they offer. That head start matters more than most of us realise: a single open-flowered bloom can supply a bee with a full meal in one visit, while a fancy double bloom may offer nothing at all.

The good news is that the three plants below are easy, widely available and genuinely beautiful. Plant foxgloves for spring, lavender for high summer, and wild marjoram to carry the garden into September, and you will have stitched a nectar seam right through the growing year.

Foxgloves: spring nectar for the first bees

Common foxglove (Digitalis purpurea) is the plant that gets a garden buzzing in late May and June, just as queen bumblebees emerge from hibernation and need food urgently. The hanging purple bells are built for long-tongued bumblebees, which crawl inside to reach the nectar and pick up pollen on their backs. Look closely at the speckled throat of each flower — those markings act as landing lights for approaching insects.

Foxgloves are biennial, meaning they grow a rosette of leaves in their first year and flower in their second. Sow seed in June or July in trays, prick out the seedlings, and plant them into their final spot by early autumn. They are happiest in dappled shade or a woodland-edge position, in soil that stays reasonably moist but never waterlogged.

• Sow thinly — foxglove seed is dust-fine and germinates generously
• Plant in groups of five or more so insects can find them easily
• Let some flower spikes set seed and you will rarely need to sow again
• All parts are toxic if eaten, so keep them away from grazing pets and small children

Lavender: the summer workhorse

English lavender (Lavandula angustifolia) takes over in July, when bee colonies are at their peak and butterfly numbers are building. Compact varieties such as 'Hidcote' and 'Munstead' are the best choices for most UK gardens: they flower earlier, stay tidier, and cope with our damp winters better than the taller French and Spanish types.

The two essentials are full sun and sharp drainage. Lavender sulks in heavy clay, so if that is what you have, dig in plenty of horticultural grit or grow it in a raised bed or a large pot. Water it well through its first summer, then leave it largely to its own devices — mature lavender is drought-tolerant and resents being fussed over.

Prune in late August, once the flowers have faded. Take the stems back by about a third, but stop short of the old, leafless wood, which rarely shoots again. This annual trim keeps plants bushy and stops them flopping open in the middle. Expect a good eight to ten years from a plant before it goes woody and wants replacing.

Wild marjoram: the late-summer bridge

Wild marjoram (Origanum vulgare) is the quiet hero of a wildlife border. From July into September it produces clouds of small pink-purple flowers held on wiry stems, and those flowers are irresistible to butterflies — particularly gatekeepers, commas and small tortoiseshells — as well as solitary bees and hoverflies.

Unlike its culinary cousins, wild marjoram is a British native, found naturally on chalk downland and dry banks. It wants the same conditions as lavender: sun, good drainage, and poor-ish soil. Rich, heavily manured ground will give you floppy growth and fewer flowers, so resist the urge to feed it.

• Sow seed in spring or buy small plants in early summer
• Plant at the front of a border where its scent can be enjoyed and insects can land easily
• Cut plants back by half after the first flush to encourage a second round of flowers
• Allow a few stems to seed around — self-sown seedlings are free and always welcome

Stitching the seasons together

The real trick is overlap. Bees and butterflies do not read planting plans, so aim for a continuous chain of open flowers rather than three separate peaks. Foxgloves hand over to lavender in early July; lavender fades as wild marjoram opens; marjoram then carries the garden into early autumn, when ivy flowers and seed heads take over.

If you have room for a few more, weave in purple loosestrife for damp spots, betony and field scabious for drier ground, and birds-foot trefoil for a low, sunny edge. Plant in generous drifts rather than single specimens — a block of one plant is far easier for insects to locate than a lone bloom among many.

Positioning matters too. Butterflies need warmth to fly, so put your nectar plants in the sunniest, most sheltered corner you have, ideally against a south-facing wall or hedge. A flat stone nearby gives them somewhere to bask and warm up between feeding visits.

Small habits that make a big difference

• Choose single, open flowers over doubles — doubles often have little or no nectar
• Leave seed heads standing through winter; they feed birds and shelter overwintering insects
• Skip pesticides entirely, including sprays aimed at aphids, which ladybirds and hoverfly larvae will handle for you
• Provide shallow water — a saucer with pebbles and a little water gives bees a safe place to drink
• Allow a patch of lawn to grow longer, or leave a scruffy corner, so solitary bees can nest in the ground

None of this requires a large garden or a lot of money. A sunny border, three well-chosen plants and a little patience are enough to turn a quiet patch into something that buzzes, flutters and rewards you from May right through to September.
