Why we love this plant!

This iconic Australian species creates strong visual interest with its blackened trunk and long, arching grass-like leaves. It produces tall flower spikes that attract native bees, butterflies, and nectar-feeding birds, enhancing garden biodiversity. Extremely drought-hardy and adapted to fire-prone environments, it’s a good option for low-maintenance native gardens across South East Queensland. Slow-growing but long-lived, this species contributes to a sense of place and connection to Country.

Care Considerations

Watering preferences:

Water deeply and occasionally, especially during dry spells. Avoid overwatering, as it prefers well-drained conditions.

Mulching preferences:

Mulch lightly around the base, keeping clear of the trunk to avoid rot.

Fertilising preferences:

Generally not necessary; if needed, use a low-phosphorus native plant fertiliser.

Pruning preferences:

Remove spent flower spikes and any damaged leaves as needed to maintain appearance.

Good to Know:

Tall flower spikes produce nectar that attracts birds, butterflies, and native bees, especially honeyeaters and beetles.
