Coastal Garden Design Ideas and Beautiful Landscapes by the Sea

by Kremy

When it comes to coastal garden design ideas, it is usually a seaside terrain. Coastal regions are distinguished by a very warm, sometimes even hot and dry climate and a specific flora. However, coastal gardens are often set up in regions with more severe weather conditions – for example, in Scotland on the shores of the English Channel, exotic plants such as palm trees may grow well.

The proximity of the sea has its pros and cons, so an individual approach is required in each case. The main disadvantage, as a rule, is rather strong winds blowing from the sea, and the salt content in the air as it may be fatal for some plants. On the other hand, the proximity of water makes the climate milder, especially in winter, so the temperature drops do not have a negative effect on plants.

In general, if you plan the landscape design properly and provide the plants with protection from the wind, you can grow quite capricious species in coastal gardens. It is not necessary to erect tall walls around the garden plot that will act as a wind shield. Planting trees and large shrubs, mainly evergreens, does an excellent job as they will protect the garden from the wind, they will not block the view of the sea and will not violate the natural harmony.

Many people are fascinated by coastal garden design ideas, especially by the romantic Mediterranean style landscapes with climbing plants, aromatic herbs, arches, gazebos and water features. If you are one of those people, let’s see how you can create a magnificent coastal garden in your backyard.

When you start planning your exterior design, you need to know what the key features of seaside gardens are. For example:

  • Easy Maintenance
  • All weather surfaces
  • Shelter and Shade
  • Lighting
  • Space for al-fresco dining
  • Water features

It is especially important to consider the location of your plot and the conditions as they will affect the plant species. Winds will naturally have a greater impact on a garden located almost on the coastline than on an area located farther from the sea. Strong winds will limit the choice of species that you can plant, and in such cases you can focus on the architectural elements of a coastal garden design – cobbled areas, courtyards, paths, etc. Of course, this does not mean that there will be no vegetation in the garden at all – you just have to limit yourself to lawns and the most hardy and unpretentious species. Delicate specimens are usually planted in containers, hanging baskets and pots and, if necessary, the plants can be brought indoors, placed under a canopy or against a wall.

Another challenging factor that you need to keep in mind is the fact that the soil in coastal gardens usually dry, sandy or stony, which means that it does not retain moisture for long after watering or rain. This means that you will need dry-loving plant species.

A variety of materials are used for paving courtyards and paths – stone, brick, decorative tiles, sandstone, wood, pavers, etc. The gaps between the slabs are filled with drought-resistant grasses.

Shade and shelter – these are important elements in a coastal garden design if you want to stay outdoors as much as possible. There are many options – pergolas, gazebos, pavilions – which will protect you from sun’s rays during the day and the wind at night.

Garden lighting is essential and you need to plan it in advance. Whether you prefer bright lights or subtle, romantic lighting, make sure it is installed prior planting.

If you have a sea view and you can hear the sound of the waves, you are really lucky. However, if you are farther from the shoreline, a water feature, small pond or pool will look very impressive in the garden.

Last, but not least, you need to choose your coastal garden style. Mediterranean, tropical, Cape cod, Gravel and rock, Cottage garden – each one has its specific features. For example, Mediterranean gardens are rich in bright colors- orange, golden, nautical blues, white, red, purple and green. You can choose a theme – nautical décor, beach and seashore, Provence, Italy, island oasis, rock garden, etc.

Plants for coastal gardens – trees, shrubs, succulents and flowers

The choice of plants for coastal gardens will depend on the location of the plot, the local climate, the style, and of course, the personal preferences of the homeowners. Brightly colored plants in flower beds are ideal for vibrant coastal gardens and they bring a pop of color to the space. If you prefer low maintenance plants, choose hardy perennials that require minimal care and attention. For example these are the plants that grow on the dunes. Usually they are low height with waxy coating which protects them from the salty sea air.

It is best if trees and shrubs are planted as soon as the garden is laid. Of course, it will take them more than one year to become adults and begin to fulfill their protective function but once they grow, you will be able to plant more capricious plants in the garden.

  • Trumpet creeper /Trumpet vine (Campsis radicans)
