Asparagus virgatus Baker
Protasparagus virgatus (Baker) Oberm.
Asparagaceae (Queensland, New South Wales, the ACT and Western Australia)Liliaceae (Victoria, Tasmania, South Australia and the Northern Territory)
asparagus fern, broom fern, tree fern
Native to eastern and southern Africa (i.e. Tanzania, Mozambique, Zambia, Namibia, South Africa and Swaziland) and the Arabian Peninsula (i.e. Yemen).
Naturalised in some parts of eastern Australia (i.e. relatively widespread in south-eastern Queensland and less common in the coastal districts of central New South Wales).
This species is regarded as a minor environmental weed in eastern Queensland and as a "sleeper weed" or potential weed in other parts of Australia (e.g. in north-eastern New South Wales). It was introduced as a garden ornamental and is still quite common in old gardens. Its potential distribution in Australia is thought to be restricted to the coastal and sub-coastal districts of New South Wales and Queensland, from Townsville in the north to Sydney in the south. It spreads via creeping underground stems to form large and dense patches that replace native vegetation. It is mainly found in riparian areas and near forest margins, or in disturbed sites and waste areas near habitation.
