A common challenge in bushland restoration is distinguishing between White Cedar (Melia azedarach) and Golden Rain Tree (Koelreuteria elegans subsp. formosana). While they may appear similar, White Cedar is a valuable native species whereas Golden Rain Tree is an invasive environmental weed.
White Cedar is a hardy, fast-growing tree that thrives in various ecosystems, playing a vital role in bush regeneration by shading out weeds. Its fruit is a crucial food source for frugivorous birds, flying foxes and possums, while its flowers attract pollinators. Golden Rain Tree, an introduced species, has been widely planted in SEQ and is now prolifically self-seeding. It establishes dense thickets in bushland, reducing biodiversity and altering natural ecosystems.
The best way to tell the difference is by looking at the leaflet arrangement – whether they are opposite or alternate.
