Designing a Cottage Garden with Native Moorland Plants

Why Native Moorland Plants Belong in a Cottage Border

The cottage garden we picture — hollyhocks against a warm wall, lupins, roses round the door — was invented on deep, crumbly lowland loam. Try that same recipe on a moorland edge, where the soil is peaty, sour and often waterlogged from October to April, and most of it will sulk, rot or blow flat. The answer is not to fight the ground with bags of lime and barrow-loads of farmyard manure. It is to build the border around plants that already grow wild within a mile of your gate.

Moorland natives bring structure, late-summer colour and enormous wildlife value. Blend them with the toughest traditional cottage flowers and you get a border that still looks generous and old-fashioned, but asks almost nothing of you in return.

Start with the Soil You Actually Have

Peaty moorland ground is usually acid — somewhere between pH 3.5 and 5.5 — low in nutrients, and either dust-dry in a dry June or squelching underfoot by Christmas. Dig a few spade-deep holes in winter before you plan anything, and see where the water table sits.

• Do not lime, and avoid mushroom compost, which is often alkaline.
• Improve the ground with composted bark, leaf mould or a pine-based ericaceous compost. These are acid-friendly and open up dense peat.
• On boggy ground, plant into low mounds of grit and compost so crowns sit above the winter water.
• Skip fertiliser altogether. Rich soil makes foxgloves floppy and heathers grey and leggy.

If your ground is thinner and stonier — a hillside over gritstone, say — drainage will be sharper and the pH a little higher, which widens your plant list considerably.

Heathers and Ferns for Backbone

Heathers give you colour from July until March, long after the last annual has gone over. Use Calluna vulgaris for late summer and autumn flower, Erica cinerea for the driest, sunniest bank, and Erica tetralix (cross-leaved heath) for the wettest hollows, where its grey foliage and pink bells look thoroughly at home. Daboecia cantabrica will flower into October in a sheltered spot.

Plant heathers in groups of five to nine of a single variety, roughly 30–45cm apart, so each clump reads as a drift rather than a dot. Shear Calluna lightly in spring; never cut back into old, bare wood, because it will not reshoot.

Ferns supply the soft green filling that makes a border feel lush. Blechnum spicant (hard fern) is evergreen and unfussy, Dryopteris filix-mas makes a bold architectural clump, Athyrium filix-femina suits damp shade, and Osmunda regalis is magnificent in genuinely boggy ground. Plant them behind the heathers as a dark backdrop.

Foxgloves: The Cottage Heart of the Border

Digitalis purpurea is a genuine moorland plant, seeding itself into acid banks and woodland clearings all over the uplands. It is the single best bridge between wild ground and cottage charm. Sow seed in June or July on the surface of a tray — light is needed for germination — or simply scatter it where you want it and let the rain do the work. Plants flower in their second year, then die, leaving behind a dusting of seed that will keep the border stocked indefinitely.

Foxgloves resent root disturbance, so move seedlings young, in autumn. On an exposed site, plant them against a wall, a bank or the lee side of a hedge, or the spikes will snap in the first gale. Leave a few seed heads to ripen before tidying, and you will never need to buy them again.

Traditional Cottage Flowers That Tolerate Poor Acid Soil

Plenty of old favourites will cope, provided you choose the right forms.

• Geranium sanguineum and Geranium macrorrhizum for free-flowering, drought-proof ground cover.
• Alchemilla mollis, spilling over path edges and seeding gently into gravel.
• Aquilegia vulgaris, short-lived but endlessly self-seeding in shades of blue, plum and cream.
• Lupinus Russell hybrids, which do surprisingly well on acid soil and give the border its early-summer height.
• Succisa pratensis and Knautia arvensis, the pincushion-flowered scabious that bees adore.
• Sanguisorba officinalis for wine-red bobbles on wiry stems in late summer.
• Luzula sylvatica as an evergreen edge, and Molinia caerulea for movement in the wind.

Layer by height: low carpeters at 30cm to the front, mid-sized plants at 60cm behind them, and foxgloves, lupins and ferns at 90–120cm at the back against the shelter.

Planting, Shelter and the Year's Work

Plant in autumn or early spring, when the ground is damp and roots can settle. Wind is the real enemy on open moorland, so provide low shelter — a hawthorn or beech hedge, or a woven hazel hurdle — rather than a solid fence, which simply creates battering eddies. Stagger groups of plants rather than lining them up, and let the heathers knit together into broad sheets.

The yearly routine is light. Shear heathers in spring. Leave perennial stems standing until March so seed heads feed the birds and shelter insects, then cut them down. Mulch with leaf mould in April, and lift and divide geraniums and alchemilla every three years to keep them vigorous. Collect foxglove seed in August and scatter it into any bare patch.

Your border will always look a touch wilder than a lowland cottage garden, and that is entirely the point. Give it three seasons, and foxgloves will be threading up through the heather on their own, ferns will be unfurling in the damp corners, and the whole thing will look as though it has been there for a hundred years.
