New Zealand Holly
Olearia macrodonta, commonly known as New Zealand Holly, is a robust, vigorous evergreen shrub ideal for large hedges, particularly in coastal or milder regions of the UK. Despite its common name, it is an aster rather than a holly, though its grey-green, leathery leaves feature crinkled, spiny margins that strongly resemble holly foliage. The undersides of the leaves are covered in a silvery-white felt, providing a beautiful shimmer in the wind. In mid-summer, it produces large, flat clusters of daisy-like white flowers with a pleasant, musky fragrance. It is remarkably tolerant of salt spray and maritime exposure, making it a staple for seaside windbreaks. It is generally hardy (H4) but may require protection in very cold inland areas. It prefers well-drained soil and a sunny position. When grown as a hedge, it can be pruned hard to maintain a dense, bushy shape, reaching heights of 3 metres or more if desired.
