Why native plants earn their place in a small garden

A courtyard, balcony or narrow strip of border is not a compromise. British wildflowers evolved alongside our insects, so they cope with competition, thin soil and unpredictable weather without feeding, staking or constant watering. Choose species whose natural size matches the space you actually have — roughly 20cm to 60cm for a pot or a tight border — and you get a garden that largely looks after itself while feeding bees, butterflies and moths.

The compact core: cowslip, foxglove and betony

Start with these three. All are hardy, all are nectar-rich, and none will bully its neighbours.

• Cowslip (Primula veris). Nodding yellow flowers on 20–25cm stems in April and May, above a neat rosette of crinkled leaves. It wants sun or light shade and soil that does not bake dry. Cowslip is one of the first serious nectar sources of the year, feeding queen bumblebees and brimstone butterflies. Sow seed in autumn — it needs a cold spell to germinate — and expect flowers in the second spring.
• Foxglove (Digitalis purpurea). Tall but narrow: a 1.5m spire occupies barely 30cm of ground. It is happiest in dappled shade, and long-tongued bumblebees work the tubular flowers through June and July. Treat it as a biennial — sow in early summer, plant out by autumn, and let some seed fall so a new generation follows on.
• Betony (Stachys officinalis). Rough-leaved rosettes and pink-purple flower spikes from June to August, around 30–45cm tall. Happy in sun or part shade and drought-tolerant once established, it is used by bumblebees, leaf-cutter bees and day-flying moths. Split clumps every few years in early spring.

Three more worth squeezing in: selfheal, a low creeper flowering from June to September that shrugs off a light trim; wild marjoram, 30–45cm and a magnet for butterflies in late summer; and harebell, whose nodding blue bells suit a sunny pot or wall top.

Shade, pots and narrow borders: how to fit them in

In shade, lean on foxglove, wood anemone, primrose and selfheal; cowslip and betony cope with part shade, especially where they get morning sun. Deep, dry shade under dense evergreens defeats almost everything, natives included.

For containers, use a peat-free compost mixed with 20–30 per cent grit or loamy soil, and pick pots at least 30cm deep with generous drainage holes. Stand them on feet so water never sits. A gravel mulch over the surface cuts evaporation, keeps liverwort down and stops rain splashing soil onto leaves. Water through the first summer, then only in dry spells.

In narrow borders, plant drifts of three to five of the same species rather than one of everything — it reads better and pollinators find the clumps more easily. Keep heights between 20cm and 60cm towards the front, with foxglove at the back for vertical interest. Skip grass-heavy meadow mixes in small spaces; they need the competition of meadow grasses and a cutting regime you cannot easily provide in a pot or a metre-wide bed.

Planting for a long season

Stagger flowering so something is always open:

• April to May: cowslip, primrose, wood anemone.
• June to July: foxglove, harebell, early wild marjoram.
• July to September: betony, wild marjoram, selfheal.
• Late season: leave seed heads standing, and treasure any ivy on a boundary wall — it is a lifeline for late bees and hoverflies.

Do not deadhead everything. Seed heads feed goldfinches and finches through winter, and hollow stems left standing give solitary bees somewhere to shelter.

Native planting for coastal, wind-battered gardens

Where salt-laden wind and free-draining soil are part of daily life, choose grey or leathery leaves and low, hugging growth. Sea thrift, 15–20cm, flowers pink from May to July and copes with spray and drought. Sea campion forms a low mat of white flowers, ideal at the front of a pot, and kidney vetch is a small, clover-like native whose yellow flowers are used by the small blue butterfly.

Wild carrot, betony, harebell and foxglove all do surprisingly well in coastal urban gardens, provided the taller ones get a little shelter. A slatted screen, a low hedge or even a sturdy planter wall takes the worst of the wind. Use gravel mulch to slow evaporation, water containers with rainwater where you can, and remember that the plants which resent salt most are soft, lush, fast growers — not the natives listed here.

Small habits that make a big difference

Leave the cutting back until late April rather than autumn. Seed heads, hollow stems and the eggs and pupae tucked into old growth are the whole point of a wildlife garden. When you do tidy, work in stages and leave a few centimetres of stubble.

Avoid double-flowered cultivars, and be wary of anything sold as a native that produces no nectar. Buy seed or plants of British origin where you can, check that a "wildflower" really is a native rather than a garden escape, stick to peat-free growing media, and never take plants from the wild.
