Olearia x haastii

Olearia x haastii is a robust, slow-growing evergreen shrub belonging to the Asteraceae family. Often referred to as the New Zealand Daisy Bush, this plant is highly prized for its dense foliage and its reliable, late-summer display of fragrant, white daisy-like flowers that bring interest to the garden when many other species have faded.

Originating from the islands of New Zealand, this hybrid has been selected for its remarkable tolerance to wind and adverse weather conditions. Its resilience makes it an excellent choice for coastal gardens or exposed locations where more delicate plants might fail to thrive, as it naturally copes with salt-laden winds.

Botanically, it forms a rounded, bushy habit with small, oval, dark green leaves that feature a silvery-white tomentose underside. This contrast provides a striking visual effect, especially when ruffled by the breeze. The flowers are small but occur in such abundance that they can virtually cover the plant, creating a blanket of white bloom.

Successful cultivation of Olearia x haastii requires a sunny position with free-draining, moderately fertile soil. It is particularly sensitive to waterlogging, which can lead to root rot; therefore, providing a porous substrate is essential. Routine maintenance involves light pruning after flowering to encourage a dense habit and prevent the base from becoming woody and bare.

In landscape use, it serves well as a structural element, a low hedge, or a focal point in a mixed shrub border. While generally pest-free, gardeners should monitor for scale insects and aphids. Overall, its hardiness and low-maintenance profile make it a sustainable choice for gardeners looking for evergreen year-round interest.
