Height and Width

  • Height: Typically grows to a height of 6 to 10 meters.
  • Width: Spreads out to a width of about 3 to 5 meters.

Soil Type

  • Soil Preference: Casuarina glauca 'Green Wave' thrives in well-drained soil with a sandy or loamy texture. It is highly tolerant of poor or sandy soils and is well-suited to coastal landscapes where salt spray and wind exposure may be present.

Plant Description

  • Foliage: The plant features unique, needle-like foliage arranged in a distinctive wave-like pattern along the branches. The foliage is a rich green color and adds texture and visual interest to the landscape.
  • Growth Habit: 'Green Wave' has an upright, columnar growth habit, with branches ascending upwards in a graceful, undulating manner. This makes it an ideal choice for vertical accents, screening, or as a focal point in the garden.

Flower Description

  • Flowers: Inconspicuous flowers may appear in spring or summer, but they are typically not ornamental or showy.

Seed Description

  • Seed Cones: Following flowering, 'Green Wave' produces small, woody seed cones that contain seeds. These cones are not typically ornamentally significant but may attract birds and wildlife.

Cultivation and Care

  • Watering: Casuarina glauca 'Green Wave' is drought-tolerant once established but benefits from occasional watering during prolonged dry periods, particularly in its first year of growth. Avoid overwatering, as this can lead to root rot.
  • Sunlight: Prefers full sun to partial shade. It can tolerate some shade but may produce less dense foliage and have a more open growth habit in lower light conditions.
  • Pruning: Prune as needed to maintain the plant's desired shape and size. 'Green Wave' generally requires minimal pruning due to its upright, columnar habit.
  • Fertilising: Generally, this plant does not require heavy fertilisation. A balanced fertiliser applied in spring can help promote healthy growth and foliage.

Additional Notes

  • Pests and Diseases: Casuarina glauca 'Green Wave' is relatively pest and disease-resistant, particularly when grown in well-drained soil and provided with proper care. However, it may occasionally be susceptible to scale insects or fungal diseases if conditions are unfavorable.
  • Uses: Ideal for use as a vertical accent, screening plant, windbreak, or focal point in gardens, parks, or coastal landscapes. Its unique foliage and upright habit make it a standout feature in any landscape setting.
