Welcome

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 Dietes, Butterfly iris

 Dietes spp., butterfly iris, or just dietes


Dietes is in the Iris family. It is native to eastern and southern Africa. Dietes has recently been appearing in bushland in south-eastern Australia. Unfortunately, it still seems to be commonly planted by Local Government Councils and in other public plantings.




Plants consist of clumps of erect sword-shaped leaves, with short-lived, iris-like flowers that are white, yellow and mauve. The flowers are followed by green, three-celled capsule containing numerous hard angular seeds.




Dietes is spread by seed via water, humans, contaminated soil (earthmoving equipment, car tyres etc) and garden refuse dumping.


Please remove spent flowers to stop seeds developing. Remove any seed-heads, and place any seed-heads or plant roots/rhizomes in your green waste (FOGO) bin, or if you don't have a FOGO (Food Organics Green Organics) bin, place them in your rubbish bin.

 

Grow Me Instead

Grass flag (Libertia paniculata





Australian native which forms a grass like clump with masses of white flowers in spring, for moist, semi-shaded positions.


Blue flax lily (Dianella spp.) 



Flax lily is native to Australia and many of the garden cultivars stem from four of the native strains. The richly-hued blue flowers with delicate yellow anthers perch like chandeliers on the end of wiry stems and contrast well with the long linear form of the leathery leaves.


Kangaroo paws (Anigozanthus species and varieties.)



Kangaroo paws originate in Western Australia. They have clumps of strappy leaves. The different varieties vary in colour, height and hardiness in our area.
