An Australian Icon - Grass Trees
Xanthorrhoea glauca, more commonly known as Grass Trees, are an iconic native Australian plant that epitomise the Australian bush. Their unique foliage provides dynamic texture and colour to any garden. They are an ultra-hardy plant option, thriving in nutrient-poor soil types and flowering in response to bush fires.
Fact Sheet
Planting
Plant in a sunny position with well-aerated soil. If opting to plant in a pot, mixing the soil with sand or gravel is recommend to aid in drainage. Daily watering should be maintained for the first month after planting, with the first few weeks of maintenance after planting being critical to ensure the plant’s health is preserved. Post-planting, water your plant well with a fertiliser mixture such as Seasol, to encourage plant health and root growth.
Flowering
Grass trees have an eye-catching ‘skirt’ of grass-like leaves with tall flower spikes being produced (often following the presence of fire). Ash from the ground assists in encouraging flower growth, which can be stimulated through smoked water or a small fire during winter (if safe to do so).
Maintenance
Grass trees require little maintenance after establishment, being almost resistant to bug infestations and needing little water. Leafy bases can either be burnt away carefully, or trimmed accordingly. If burning, ensure to follow safety procedures and be aware of government fire regulations. The plants are extremely slow growing, but they provide a great feature for your garden and can be enjoyed for decades to come.
