About
Asparagus aethiopicus, Sprenger's asparagus, is a plant native to the Cape Provinces and the Northern Provinces of South Africa. Often used as an ornamental plant, it is considered an invasive weed in many locations. Asparagus fern, asparagus grass and foxtail fern are common names; however, it is unrelated to true ferns. A. aethiopicus has been confused with A. densiflorus, now regarded as a separate species, so that information about A. aethiopicus will often be found under the name A. densiflorus.
How to grow it
Asparagus aethiopicus is grown as an indoor plant in cooler climates, or as an ornamental garden plant in urban gardens, rockeries or in pots. Two cultivars are seen in cultivation, 'Sprengeri' is a scrambling form with sparser foliage, while 'Meyeri' has more erect stems to 70 cm (28 in) and denser foliage.
Consuming the berries of A. aethiopicus can cause gastrointestinal symptoms such as diarrhea, vomiting and abdominal pain, and contact with the skin may cause dermatitis. The plant is toxic to domestic cats and dogs.
Where it grows
Asparagus aethiopicus is native to southern regions of South Africa, mainly in the Western Cape, Eastern Cape and the Northern Provinces.
