Protasparagus plumosus, Protasparagus setaceous
A very popular indoor plant because of its ability to withstand low light and neglect, this plant is naturalised in sheltered sites and rainforests infesting many hectares on the NSW coast.
Origin: South Africa
Habit: Tough, perennial, wiry, twining climbing vine with occasional spines and fine, feathery fern like foliage.
Leaves: Fine, feathery, leaf-like cladodes arranged in horizontal sprays.
Flowers: Flowers are small, greenish-white and arranged at the tips of branches in Summer.
Fruit: Bluish-green berries to 0.5cm across that turn black when ripe in Autumn.
Roots: A tough, woody crown is forged at base of stems, with a comprehensive fleshy root mass radiating out from the crown.
Dispersal: Seed spread by water, animals, birds, humans, contaminated soil (earthmoving equipment, car tyres etc) and garden refuse dumping.
Control: Difficult to control - crowning, ensure that the crown is removed off site. Remove and bag berries. Follow-up - hand -pull all emerging seedlings. Foliar spray.
