Why the Cottage Border Works

The traditional cottage garden border looks effortless, but the secret is really just careful layering. Rather than planting one flush of flowers and waiting eleven months for it to happen again, you build a border from three or four different groups of plants that each take their turn in the spotlight. Flowering shrubs give structure and early interest, perennials carry the summer, annuals fill the gaps between them, and bulbs slip into the ground beneath everything else. Get the mix right and something is always doing something, from February right through to the first hard frost.

The other great virtue of this approach is forgiveness. Cottage planting is generous and a little loose, so if a perennial sulks or a shrub grows faster than you expected, nothing collapses. You simply move things about in autumn, split what has got too big and tuck in something new.

Start With the Bones: Flowering Shrubs

Shrubs are the framework of the border, and they earn their space by flowering when little else will. Aim for roughly a quarter of the border in shrubs and give each one room to reach its natural shape rather than hacking it back every year.

• Viburnum tinus — evergreen, with clusters of pink-budded white flowers from late autumn into spring. Tolerates shade and poor soil.
• Daphne mezereum — small, deciduous and fragrant, flowering on bare stems in February and March. Needs sharp drainage and alkaline soil to do well.
• Philadelphus — the mock oranges. Plain green leaves, but the white flowers in June and July scent an entire garden.
• Hydrangea paniculata — flowers from late July into October, turning from cream to pink. Prune hard in March for bigger heads.
• Rosa — a repeat-flowering shrub rose such as a gallica or an English-style shrub rose will give you scent and cut flowers for months.

Plant shrubs in autumn or early spring, water them well through their first summer and mulch with well-rotted manure. After that they mostly look after themselves.

Perennials for the Long Middle Season

Perennials are the heart of the border. Choose a spread of flowering times rather than a single glorious fortnight, and aim for a mix of spires, daisies and soft mounds so the border has shape as well as colour.

• Late spring: hardy geraniums, Iris sibirica, peonies and oriental poppies.
• Early summer: lupins, delphiniums, Alchemilla mollis, campanulas and catmint (Nepeta).
• High summer: crocosmia, phlox, heleniums, daylilies, scabious and Echinacea.
• Late summer and autumn: asters, sedums, rudbeckias, Japanese anemones and heleniums again if you deadhead.

Deadheading is the single most useful thing you can do. Cut spent flower stems back to a strong shoot and many perennials, especially geraniums and nepeta, will give you a second, smaller flush in September. Leave a few seedheads standing for the birds and for winter structure.

Annuals and Biennials to Fill the Gaps

This is where cottage gardening leaves formal planting schemes behind. Annuals are cheap, quick and forgiving, and they let you change the border's mood each year without lifting a spade.

Sow hardy annuals in September or early October for bigger, earlier plants, or in March and April for a later show. Good, unfussy choices include calendula, cornflowers, nigella, godetia and annual poppies. Among the half-hardy sorts, cosmos, nicotiana and cleome will flower from July until the first frosts if you keep picking them.

Biennials such as foxgloves, wallflowers and honesty are worth the wait. Sow them in early summer in a nursery bed, move them to the border in autumn, and they will fill the gap between the spring bulbs and the first perennials. Foxgloves also self-seed happily, which is exactly what you want in a cottage border — just be prepared to pull out the seedlings that appear where you don't want them.

Bulbs: Small Investment, Big Return

Bulbs are the cheapest way to extend the border's season in both directions. Plant them in generous drifts rather than tidy rows, and let the foliage die down naturally for six weeks before you cut it.

• February to March: snowdrops, winter aconites and dwarf iris.
• March to April: daffodils, grape hyacinths and Anemone blanda.
• May: tulips, especially the species types, which come back more reliably than the big bedding varieties.
• Late summer: Colchicum and autumn crocus for a surprising flush just as everything else is fading.

Plant spring bulbs in September and October, roughly three times their own depth, and mark the spots so you don't spear them later with a fork.

Soil, Staking and Keeping It Looking Loose

Cottage borders do best in reasonably fertile, well-drained soil in full sun, though most of the plants above will manage in light shade. Improve your soil with two or three inches of garden compost or well-rotted manure each spring and the whole border will need far less watering.

Feed perennials with a general-purpose fertiliser in March and again in early summer. Tall plants such as delphiniums need staking, but do it early, using twiggy hazel pea sticks pushed in while the shoots are still short — it looks far more natural than canes and string, and the plants grow up through it.

Finally, resist the urge to tidy in autumn. Leave seedheads, hollow stems and the last of the foliage standing until March. It feeds the birds, shelters overwintering insects and, on a frosty morning, looks every bit as good as the summer border did.
