Plants for Seaside Gardens

There is a great range of plants which grow well in seaside gardens. The milder conditions allow the seaside gardener to grow plants which would not thrive in some more exposed areas of the UK. 

Many of these plants need little or no maintenance, which can be important if the house and garden are not occupied all the year round. Plants need to be self sufficient.

Below are ideas, images and growing tips for Seaside Gardens.
