Weed of the Month: Leucaena leucocephala
By Rae Wear (Rae is from the Native Nursery on Coochiemudlo Island)
Leucaena leucocephala is among the top 100 most invasive species worldwide.Growing up to 10 meters high, with long canes and compound, ferny green leaves. The fluffy, cream, wattle-like flowers are followed by pods that turn from green to brown. Each pod contains up to 25 seeds, which are dispersed by animals, wind or water. Leucaena supplants native vegetation and is difficult to eradicate once established. It grows all over Coochiemudlo but is most prolific on the island's Western side on the Emerald Fringe and around the Community Hall. It is native to Central and South America and was planted for fodder in Queensland. Its further spread was encouraged when the Japanese Imperial Army introduced it as camouflage to many Pacific Islands during World War II.
Native alternatives
Native alternatives are Acacia fimbriata (Brisbane wattle), Hakea florulenta or Melaleuca sieberi.
