Mediterranean landscape design

The palette is dominated by aromatic, small-leaved shrubs that evolved for drought: lavender, rosemary, santolina, cistus, phlomis, thyme and germander, most of them silver or grey-green rather than fresh green. Above them sit olive trees with their pale leaf undersides, bay, and citrus grown in pots so it can be moved under cover. Italian cypress supplies the dark exclamation marks, and the eye needs only two or three of them. Colour is used sparingly — bearded iris in spring, agapanthus in summer, bougainvillea on a warm wall where the winter allows. Almost everything on this list is evergreen, so the garden reads much the same in February as in July, which is the practical argument for the style in a climate that suits it.

The surface is gravel or decomposed granite far more often than lawn, and plants are allowed to seed into it. Paving, where it appears, is tumbled brick, limestone, or reclaimed stone laid loose with wide joints planted with thyme. Terracotta does the ornament: large unglazed pots, olive jars used as full stops at the end of a path, and shallow bowls of succulents on a wall. Walls are rendered and lime-washed rather than fenced, dry-stone where the site has a level change. Shade is architecture here — a pergola with a grape vine or wisteria over a table is the functional centre of a Mediterranean garden, because the design assumes people eat outside in the heat rather than sit in the middle of a lawn.

The style belongs to dry-summer climates: coastal and inland California, the Southwest and parts of Texas, broadly USDA zones 8 to 10 as drawn on the USDA Plant Hardiness Zone Map. Olive takes brief cold to around 15°F, so zone 8 is realistic and zone 7 is a gamble in a hard year. The more common failure has nothing to do with hardiness. Lavender, cistus, santolina and rosemary die of root rot in heavy soil that stays wet through winter, which is why the same plants that thrive in Sacramento collapse in Atlanta or Seattle. If the style is wanted in a wet region, the fix is drainage rather than plant substitution: raised beds, coarse grit worked through the soil, and a gravel mulch that keeps crowns dry.

The first two summers need real irrigation while roots go down, and that is the stage most people skip before deciding the plants were faulty. After that, deep watering every three or four weeks in the dry season is enough, and overwatering is the more common mistake. Lavender and santolina are cut back by about a third after flowering every single year; skip two years and they go woody at the base and never recover. Olives are thinned rather than shaped. Year one is thin, with gravel dominating, and the pots are what make it look finished. By year five the shrubs have merged into low mounds, the olive has a trunk worth looking at, and the gravel has largely disappeared. The honest downside is that this garden is dull in high summer if it depends on flowers, so it has to be built on foliage and shape.

Gravel over most of the ground is the decision people hesitate over, and it is very hard to picture from a sample bag. AI Landscape Design renders Mediterranean from a photograph of your yard, keeping the house, fence and driveway exactly where they are, so the amount of gravel and the position of the pots can be seen at your own scale. The app is published by Skyble Lab and ships 18 styles in total, which makes it easy to compare this one against a drier alternative such as xeriscape using the same source photo. What it will not do is test your drainage, cost the paving, or know that your winter soil sits wet — and those decide whether this style survives at all. Download AI Landscape Design to try it.
