Wharawhara, Shore Astelia

Astelia banksii, commonly known as Wharawhara or Shore Astelia, is a striking New Zealand native plant celebrated for its silver-grey, strap-like leaves that arch gracefully. Forming dense clumps up to 1.2 metres in height and width, it brings texture and visual interest to gardens year-round. This evergreen perennial thrives in full sun to partial shade and prefers well-drained soils, making it ideal for coastal gardens, borders, containers, and mass plantings. In spring, Astelia banksii produces small, pale green flowers, followed by purple-black berries in autumn, which attract native birds. Its tolerance to wind, drought, and coastal conditions, along with low maintenance requirements, makes it a versatile choice for various garden styles, including modern, native, and architectural designs.

Growing Astelia banksii

To grow Astelia banksii successfully, choose a well-drained location with partial shade to full sun. The soil should be rich in organic matter but not overly wet; raised beds or sloped areas are effective in avoiding root rot. Water regularly during dry spells, especially while the plant is establishing, but avoid overwatering. Astelia banksii is wind-tolerant and moderately frost-hardy, making it suitable for coastal or exposed gardens. Remove dead leaves as needed, and apply mulch to retain moisture and suppress weeds. Feeding with a slow-release fertiliser in spring will encourage healthy growth. It's ideal for mass planting, containers, or as a feature plant in modern landscapes.

Astelia banksii care tips

Astelia banksii grows best in well-drained soil rich in organic matter, although it will tolerate poorer soils if drainage is adequate. When planting, it's essential to keep the crown above the soil line and avoid waterlogged or heavy soils, as this species can be prone to root rot. Regular watering is needed during establishment, but once settled, Astelia banksii becomes relatively drought-tolerant. Apply a layer of mulch around the base to retain moisture and suppress weeds, keeping it clear of the crown. Feeding in early spring with a slow-release fertiliser or compost encourages vigorous growth. While generally pest-free, removing old or damaged leaves periodically will keep the plant looking its best. It is tolerant of wind and moderately frost-hardy, making it suitable for a wide range of landscapes, including coastal and exposed gardens.
