Plants for Coastal Gardens

The South Australian Branch have produced this Fact Sheet containing many plants for coastal gardens which gardeners throughout the mediterranean climate regions will find highly useful.

For additional information about coastal planting see Helene Pizzi's article The Mediterranean Miracle Continues: Planting Coastal Gardens in the Sand, in The Mediterranean Garden No. 41, July 2005, where she describes how the dunes close to Rome have been successfully planted.

Depending on how close you are to the sea and how exposed your garden is, there are several problems you will need to deal with; the worst being high salt levels both in the soil and carried by wind and water sprays, physical damage from strong winds and fine sandy soil drying out and becoming non-wettable.

A barrier that prevents or slows down the prevailing wind is therefore paramount in a coastal garden. If you have the space, growing a mixture of hardy salt and wind tolerant trees and shrubs (especially those native to the area) as frontline protection is the best long-term windbreak. Adding organic materials to the soil, using surface mulches and slow release fertilisers as well as drip irrigation, plastic or shade cloth tree guards and wetting agents if necessary will all help plants establish and grow. And many plants once established can withstand quite severe conditions.

The plant lists below are a small selection of attractive and hardy low water use plants suitable for most South Australian coastal conditions. Eventual size and growth rate can vary enormously so check plants growing in your area or seek professional advice

Succulent Species
Most succulents are ideal for seaside gardens. They can be used in carefully chosen sites that allow leaves and flowers to stand out complementing other plantings, in large patches of a single species or as potted plants on paved areas. All succulents have the potential to become pest plants in sand dunes.
