Astelia Silver Spear (Kakaha)

Astelia Silver Spear, commonly known as Kakaha) features striking silver foliage that is held in a gentle arch. It typically grows to 1.5 m tall and the same wide, performing best when planted in full sun on a well-drained site. Astelia Silver Spear is great for providing a striking display with its stout nature and bold colouring. It makes a great contrast with other darker-coloured foliage plants and is favoured by landscape designers who often include it in mixed plantings.

How to grow Astelia Silver Spear

To grow Astelia Silver Spear successfully, select a location with well-draining soil and partial to full sun exposure. A well-drained soil is essential for success; therefore, avoid areas prone to waterlogging and those with excessive moisture. Water the plant regularly while it is establishing, then reduce the frequency as it becomes more drought-tolerant. Mulch around the base helps retain moisture and suppress weeds, but avoid piling it directly against the crown to prevent rot. Apply a slow-release fertiliser in spring to encourage healthy growth.

Astelia Silver Spear care

Astelia Silver Spear thrives in well-drained soil and prefers partial shade to full sun. In coastal regions, it tolerates full sun well and handles wind exposure with ease. The soil should be rich in organic matter but free-draining, as Astelia dislikes sitting in waterlogged conditions. When planting, ensure the crown sits just above soil level to reduce the risk of rot. Water the plant regularly while it is establishing, then reduce watering as it becomes more drought-tolerant. A yearly application of slow-release fertiliser in spring will encourage healthy growth and intense foliage colour. Apply mulch around the base to retain soil moisture and suppress weeds, but avoid covering the crown. It is generally low-maintenance, with few pest or disease issues. Remove any damaged or dead leaves as needed. It is moderately frost-hardy and ideal for modern gardens, coastal landscapes, and large containers, where its sculptural form can make a lasting impression.
