An attractive relatively short-growing member of the Xanthorrhoea genus with long grass-like leaves 2-6 mm in diameter.

The individual flowers are white/cream and very small, clustered together in a spear-like spike, 1-1.5 m high.

A food source for nectar-eating birds and butterflies when in flowers and seed-eating birds when the seed is developing.

Grass trees are widely recognised throughout the world as being uniquely Australian.

Endemic to a small region of South Australia, including Kangaroo Island.

Prefers light well-drained soil in an open sunny position. Drought and frost-resistant.

Although seed can be sown most of the year in many parts of Australia seed is generally best sown in spring or autumn, avoiding the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C for this species.

Xanthorrhoea germinate readily from seed with no special pre-treatment.

  1. Sow seed on the surface of a porous seed-raising mix and cover to a depth of 1-2 mm. Do not bury the seed deeply.
  2. Water with a fine mist spray to avoid disturbance of the seed.
  3. Place in a warm shaded or semi-shaded position to avoid dying out.
  4. Keep warm & moist, and avoid drying out or waterlogging the growing mix.
  5. Germination generally occurs in around 10-28 days in the right condition.

General note: Seeds of many natives are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they are discarded.
