Shrubs are the main structural element of any garden, after trees. In a coastal garden, they may form an intrinsic part of a shelterbelt or wind break strategy. They give form and hide boundaries etc. A coastal garden without sheltering shrubs is unlikely to create effective microclimates that give rise to a wider diversity of planting and wildlife.
Viburnum tinus, Escallonia, Euonymus japonica and Grisellinia are some of our frontline stalwarts.
