The grass tree Xanthorrhoea is a uniquely Australian plant, which epitomises the Australian landscape and is as tough as goats' knees. It will withstand drought. Bushfires will burn the foliage and blacken the stump, but then it regrows. In fact often a bushfire will encourage flower development.When it does flower, it produces spikes, which can grow up to two metres and which eventually turn brown. Just tap the seeds onto a seed raising mix, cover lightly, water and before long, you will have a new crop of Xanthorrhoeas . Don't expect miracles, because it can take 20 years for just a trunk to form .... and it will take years for one to reach its full height.
