A field study on North Stradbroke Island noted increased root growth in autumn (around April), but that overall root growth was more constant than other species looked at, possibly because its deeper roots had more regular access to groundwater.
Research conducted on North Stradbroke Island revealed that the plant's root system experienced increased expansion during the autumn months (approximately April), whereas overall root development remained relatively consistent compared to other species studied, likely because of its more stable and accessible water supply through its deeper roots.
