Chatham Island Akeake

Olearia traversii, commonly known as the Chatham Island Akeake, is an evergreen shrub or small tree belonging to the Asteraceae family. It is distinguished by its dense, upright habit and leathery leaves, which are dark green on the surface and covered with a distinctive silvery-white tomentum on the underside. This silvery coating is highly ornamental, causing the foliage to shimmer as it moves with the wind.

Native to the Chatham Islands of New Zealand, this plant has evolved to thrive in harsh, exposed coastal environments. It is well-adapted to high wind speeds and salt-laden air, which makes it a preferred choice for landscaping in coastal regions worldwide. It thrives in temperate maritime climates and generally requires protection from severe frosts to maintain its evergreen foliage.

Cultivation of Olearia traversii requires a site with full sun and well-drained, fertile soil. While it is hardy and capable of surviving in various soil types, it is particularly intolerant of waterlogged conditions, which can lead to root rot. After initial establishment, the plant is relatively drought-tolerant, though moderate watering during prolonged dry spells in the growing season promotes better density and growth.

The primary economic and landscape use of this plant is as a windbreak or shelterbelt. Due to its dense branching structure and salt tolerance, it is exceptionally effective at protecting gardens and agricultural fields from coastal gales. It is also frequently utilized as a hedge plant that can be sheared to shape, providing both privacy and a robust boundary in difficult environmental conditions.

Maintenance involves routine pruning to encourage thickness and the removal of dead wood to ensure good air circulation within the canopy. The most significant threats to its health include fungal root pathogens resulting from poor soil drainage. Pest issues are relatively minor but may include infestations of scale insects or aphids during particularly dry seasons. Keeping the soil well-aerated is the best preventative measure.

• Excellent tolerance to salt spray and winds.
• Silvery leaf undersides for aesthetic appeal.
• Requires well-drained, non-waterlogged soil.
• Ideal for coastal windbreaks and hedges.
