Wilderkind and Mystic Outlands: Rewilding Your Garden, Scottish Coast Edition

Two things happen to a coastal plot that don't happen inland: salt lands on it, and it dries out faster.

Salt spray reaches up to 200 metres inland, according to gardenuk.co.uk, and within the first 50 metres the concentration is high enough to scorch leaves and draw moisture from roots directly.

Wind is the second problem. Coastal sites run at wind speeds 30 to 50 per cent higher than comparable inland plots. Higher wind means faster evaporation from the soil surface, so plants experience drought even when rainfall is adequate.

Inside the 50-metre line, only the most salt-tolerant species survive without protection. Further back, the plant list opens up, but the wind effect persists across the whole plot.

Both conditions change what your soil can support, independent of its chemistry.

The plants that belong here

Scotland has over 1,600 native wildflower species, according to About Argyll.

Four species do the work reliably. Thrift (Armeria maritima) grows in cliff-edge crevices and tolerates salt-laden air better than almost anything else in the native flora. Sea campion handles the same conditions and seeds itself freely once established. Kidney vetch fixes nitrogen and feeds early bumblebees.

NatureScot's Planting for Pollinators guidance names all four as candidates for Scottish coastal garden native plants schemes, and it is the best starting point for checking whether a species is appropriate for your specific stretch of coast.

They evolved on ground that gets battered. What they cannot do is compete with vigorous imported grasses, which is why the soil comes next.

Why low fertility is the goal

The instinct, when you see thin grey soil, is to improve it. Bag of compost, handful of fertiliser, job done. Do that here and you'll grow grass.

Rich soil hands the advantage to aggressive species: cock's-foot, false oat-grass, creeping bent. They move fast in fertile ground and they crowd out everything you actually want. Wildflowers evolved for the lean conditions.

A free-draining, low-nutrient coastal plot is already where you want to be. The coast has done the work for you.

If any area of your plot has had topsoil or compost brought in, strip it back before you sow. Imported material raises fertility and changes the drainage. Get it off and work with what was underneath.

The windbreak first, everything else second

Get the shelter right before you plant anything else. In the most exposed strip of a coastal plot, even salt-tolerant natives die back faster than they establish if wind is constant.

Sea buckthorn is the most useful option: deciduous, tolerant of salt spray, and it produces the orange berries that define the Wilderkind palette in autumn. Elder and hawthorn both establish well behind it.

One plant to avoid: Rhododendron ponticum. It looks like an obvious coastal hedge, tough and evergreen, and it is all over the Scottish countryside for exactly that reason. It is also a listed invasive species, and the Argyll Community Trust used £214,000 of Scottish Government Nature Restoration Fund money in 2022 clearing it from a single site in Argyll.

Plant it now, spend a decade managing it later.

Two metres of hawthorn changes what survives

A packet of thrift grown from southern English stock may germinate well and then die back in the first hard winter, because the genetics are calibrated for a milder baseline.

NESBiP names three suppliers worth knowing: Scotia Seeds, the Habitat People, and Curam Fyvie. All source Scottish coastal garden native plants from within Scotland.

Locally collected seed carries the cold-tolerance and salt-exposure adaptations of its parent population. Seed from warmer regions does not, however similar the species looks on the label.

If you want to go further, NESBiP publishes a guide to collecting seed yourself from wild plants in northeast Scotland. It covers drying, and storage.

Start with one square metre

The Wilderkind and Mystic Outlands feeds do not show the planning. They show a single tuft of thrift wedged into a stone wall, one sprawl of sea campion in pale gravel, one October-sown patch that came through.

Find the most sheltered corner of your plot. Clear any imported topsoil or compost. Then order a provenance-correct coastal mix from one of the suppliers and sow in autumn, when coastal conditions most closely match what the seed expects.

That is the full first-year task for rewilding your garden on the Scottish coast. One square metre.

Scotia Seeds lists its dispatch dates on the website. If you order now, you will have the mix in hand before the ground closes.

Thrift, in particular, needs a cold period to break dormancy, so sowing late is better than sowing in a warm spell and wondering why nothing moves in spring.
