Description

Xanthorrhoea australis – Austral Grass Tree

Family: Asphodelaceae
Packet: 10 seeds

Description

Xanthorrhoea australis is a distinctive Australian grass tree with a crown of long, narrow leaves that can develop above a slow-growing trunk. Mature plants may produce tall spear-like spikes densely packed with tiny cream-white nectar-bearing flowers.

Key Features

• Flower Colour: Cream / White
• Plant habit: Slow-growing trunk-forming grass tree
• Garden interest and important notes: Its strong silhouette is highly valued in native gardens. Growth is slow and plants raised from seed can take many years to develop a prominent trunk.

Growing Conditions

• Position: Full sun to part shade.
• Soil: Very well-drained soil; avoid sites prone to standing water.
• Water: Moisture for young seedlings while establishing, with good drainage; reduce excess watering as plants mature.
• Climate: Temperate Australian conditions where suited to the species and local provenance.

Seed Propagation

1. Prepare: Use mature, fresh seed; pretreatment or smoke treatment is not normally needed.
2. Sow: Sow on well-drained native seed mix and cover only lightly.
3. Germination conditions: Keep evenly moist but never waterlogged; a bright sheltered position suits germination.
4. After germination: Handle young root systems carefully and expect slow growth.

Seed is for cultivation; native seed collection and movement should comply with relevant state and local requirements.

Germination advice: These instructions are a recommended guide. Germination results and timing may vary depending on seed freshness, storage, temperature and growing conditions. Alternative propagation methods may also be successful.
