Landcare is a non-governmental community movement dedicated to preventing land degradation and achieving sustainable land management. It consists of a network of local volunteer groups of which there are over 1700 in New South Wales alone. Each group works to find local solutions to local problems such as salinity, soil degradation, animal pests, weeds, vegetation loss, waterside erosion, poor water quality, coastal degradation and urban land degradation. If you appreciate how lucky we are in the Helensburgh district to enjoy a relatively unspoiled bush environment you should also be aware that it is under serious threat. read more

Be Weed Wise - Ginger Lily

Ginger lily (Hedychium gardnerianum)

Ginger lily is native to the Himalayas. It is now naturalised in bushland areas on the east coast. Ginger lily is also very poisonous to grazing animals, and can be fatal if enough of the plant is ingested.

Ginger lily grows to 2m tall, with long strap like leaves and large spikes of perfumed flowers. This plant forms clumps with deep matted roots. It is found in moist places. Flowers are bright yellow, fragrant and appear in summer to autumn. It grows most abundantly in open, light-filled habitats, but can grow into deep shade. It forms vast, dense, colonies that smother and displace native groundcover vegetation.

Dispersal: Clumps spread rapidly from underground rhizomes. The seeds are readily dispersed by birds and other animals that are attracted to their bright colours.

Removal: Plants can be dug up or pulled out depending on size, but the entire plant, including pieces of rhizome, needs to be removed to avoid regrowth. Seeds and rhizomes should be placed in the red bin. (Update, now that Wollongong Council has FOGO, seeds and rhizomes can be placed in the green FOGO bin.) Leaves and stems can be put in the green bin.

Grow Me Instead

Gymea lily - Doryanthes excelsa. This local native plant thrives in poor sandy soils and full sun or partial shade. The red trumpet-like flowers are borne in a terminal head 300 mm in diameter on a leafy flowering stem 2–4 m high.

Swamp lily - Crinum pedunculatum. This Australian native plant has rosettes of broad leaves and clusters of white, highly fragrant, flowers on 1m stems. Suits any soil, full sun or dappled shade and is mildly frost tolerant, it also grows well near ponds.
