Declared Noxious Weed
Usually has shortish, more or less prostrate stems whereas most other weedy Asparagus species tend to have more elongated erect or climbing stems. Note that the cultivar Meyers has erect stems with dense, short branchlets - what is commonly called a 'foxtail' stem; that cultivar is not known to be naturalised. Previously called A. densiflorus in Australia, but that name applies to a separate African species not known to be introduced here. A declared noxious weed on LHI.
