5+ exotic trees for coastal shelter
Also surviving well in this zone are some exotics which evolved in foreign coastal environments. All these are truly coastal in less extreme areas, but down here in the south they get burned off the nearer you get to the sea.
Most pines, especially P. radiata, P. Torreyana and Pinus pinea. 3. Grey and red alder ( Alnus incana, Alnus rubra) are as tough as old boots, but I would avoid black alder as it deserves to be called a weed. 4. Leyland cypress ( Cupressus x leylandii) and macrocarpa ( Cupressus macrocarpa) are good at surviving salt wind - they may not grow straight enough for timber, but will bush out nicely and form a solid wall many metres high. 5. Feijoa ( Feijoa sellowiana), my favourite of all, and it will fruit on the downwind side.
