Full of sunshine, sand and salty air, the coastal lifestyle is a coveted one, but when it comes to gardening, the coast can present its challenges. Hardy plantings equipped to grow in sandy soils and withstand buffeting winds are essential to a well-designed coastal garden, and fortunately, there are a range of plants that can not only thrive in these conditions but look good doing it too.

Spanning Australia and New Zealand, these inspiring gardens by the coast embrace their surroundings and provide the perfect atmosphere for lounging, entertaining, and alfresco dining by the sea.

What is a coastal garden?

A considered and flourishing coastal garden is able to cope with salt exposure, high winds and sandy soils that donโ€™t hold water or nutrients. Thatโ€™s why thriving coastal gardens embrace natural and organic design and Australian natives appropriate to their climate, such as banksia, grevillea, kangaroo paw and acacia.
