Grass Tree

Xanthorrhoea johnsonii is a slow-growing plant, typically reaching heights of 2–5 metres over many decades. The trunk, formed by the accumulation of old leaf bases bonded with natural resin, provides a distinctive blackened appearance. The crown consists of long, narrow leaves that radiate in a dense tuft, creating a striking contrast against the trunk. Flowering occurs on tall spikes that emerge from the crown, usually after fire events or in response to stress, producing nectar-rich blooms that attract pollinators.

Grass Trees prefer well-drained soils and are highly tolerant of drought and poor soil conditions. They thrive in full sun to partial shade. When planting, it's essential to minimise root disturbance and ensure proper drainage to prevent root rot. Watering should be moderate, allowing the soil to dry out between waterings. Fertilise sparingly with a low-phosphorus native plant fertiliser. Mulching around the base can help retain moisture and suppress weeds, but avoid piling mulch against the trunk to prevent rot.
