Learn About Your New Xanthorrhoea

Xanthorrhoea species, iconic to Australia, are known for their extraordinary form - a thick, woody trunk crowned with a dense tuft of grass-like foliage. The common name, Grass Tree, is derived from their grass-like leaves, and their remarkable ability to survive fires. They are not only a striking sculptural element in the landscape but are also of cultural significance to Indigenous Australians.

Common Name: Grass Tree
Mature Height: Depending on the species, can range from 1 to 6 meters in height, with very slow growth rates.
Mature Width: The leaf crown can spread 1-3 meters across.
Spacing: Plant at least 2-3 meters apart from other plants, as they need space to accommodate the spread of their foliage.
Foliage: Long, linear, grass-like leaves that form a skirt around the trunk.
Flowering Period: When mature, they produce a spectacular flower spike that can be up to 2 meters in height, with white to creamy flowers that attract nectar-feeding birds and insects.
Form/Habit: A singular trunk with a tufted head of grass-like foliage. The trunk is often blackened by bushfires, hence the name Blackboy.
Uses: Used as a feature plant in gardens and landscaping, their dramatic appearance is a highlight in native and xeriscape gardens.
Evergreen/Deciduous: Evergreen, providing year-round interest.
Tolerates: Very tolerant of poor soils, drought, and fire.
Drought Hardy: Extremely drought-resistant once established.
Sun: Prefers full sun but can tolerate light shade.
Maintenance: Very low; requires minimal pruning and care once established.

Additional Information

  • Soil Preferences: Thrives in well-drained, sandy or gravelly soils. Avoid soils that retain moisture.
  • Watering Needs: Water sparingly; too much water, especially in poorly drained soils, can lead to root rot.
  • Wildlife Attraction: Flowers attract a host of wildlife, including bees, butterflies, and birds.
  • Propagation: Generally propagated from seed but can be slow and requires patience. Division of clumps is possible but can be difficult and should be done by experts.
  • Pests/Diseases: Resistant to most pests and diseases. Root rot can be a problem if the soil is not well-drained or if overwatered.
  • Landscape Design Tips: Plant as a standalone feature or amongst low-lying shrubs to create a varied height landscape. They can also be used effectively in rockeries.

Planting Tips for Xanthorrhoea

Planting Your Grass Tree:

  1. Select the Right Site: Full sun with excellent drainage is crucial for healthy growth.
  2. Prepare the Soil: Loosen the soil and ensure it is free-draining. Consider raising the planting area to improve drainage if necessary.

Growing Xanthorrhoea in Various Soil Types

How to Grow Grass Trees in Different Soil Types

Grass Trees require excellent drainage.

Here’s how to manage different soils:


Ideal. Minimal preparation required.


Not suitable unless modified. Improve drainage by raising the planting area and incorporating coarse sand or gravel.


Suitable, provided water doesn’t pool. Create a mound if needed.


Acceptable if well-draining. Dig wide enough to accommodate root mass.

Avoid wet, boggy, or compacted areas. Raised beds or mounded plantings are strongly recommended for problematic sites.

Watering Requirements After Planting Your Xanthorrhoea

When planting a new tree or shrub, proper watering is essential to ensure healthy establishment and long-term growth. Follow these guidelines to give your plant the best start:

  1. Immediately After Planting:
    Water generously right after planting to settle the soil around the roots and eliminate air pockets. This helps the roots make good contact with the soil.
  2. First Three Months (Establishment Phase):
    The initial three months are critical for root development. Water deeply twice daily (morning and evening) to encourage strong, deep root growth.
  3. Irrigation Systems:
    If using an irrigation system, adjust it to provide adequate water during the establishment phase. Ensure the water reaches the root zone without overwatering.
  4. Weather Considerations:
    Adjust watering based on weather conditions. Increase frequency during hot, dry periods and reduce it during cooler, wetter seasons.
  5. Ongoing Care:
    After the establishment phase, gradually reduce watering frequency but ensure the plant receives consistent moisture, especially during dry spells.

By providing consistent and appropriate watering during the initial months, you’ll help your new tree or shrub establish a strong root system and thrive in your garden.
