Tuffed Grass Tree
Other names: Blackboy or Yakka
Characteristics: Perennial monocot 1-1.5m
Seeds per packet: 10
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 a light well-drained soil in an open sunny position. Drought and frost resistant.
Although seed can be sown most of the year in Australia seed is generally best sown in spring or autumn, avoid 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.
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 were discarded.
