Metrosideros excelsus

The New Zealand Christmas Tree.

Very wind hardy but quite tender.

Olearia

Lots of variety here and plenty of different leaf styles to suit most people.

Eleagnus

Again good choice and very tough to wind and cold

Escallonia

Not really recommended for right on the beach but a fast grower usually with red flowers.

Cordyline australis

The cabbage palm. Very good for wind but protect from severe frost.

Phormiums

Again from New Zealand. For very exposed sites stick to plain green varieties.

Cordateria

Pampas grass
