Naming
Foxtail asparagus is part of a group of similar-looking and related "Asparagus" species native to Africa, including "Asparagus aethiopicus", "A. confertus" and "A. krebsianus"."A. densiflorus" has been occasionally confused with "A. aethiopicus"—a different, spikier, more rambling and pendant species—thus some sources provide incorrect information in reference to "A. densiflorus". The plant formerly often grown as "A. densiflorus" var. 'Sprengeri' is, simply, "A. densiflorus". Furthermore, the species known as "A. densiflorus" var. 'Meyersii' remains "A. densiflorus", as well.
As a whole, the "Asparagus" genera is part of a larger botanical order, the Asparagales, which groups together other related plant families such as the agaves, cordylines, dracaenas, orchids, ponytail palms, snake and spider plants, and yuccas.
Distribution
"Asparagus densiflorus" is native to the Cape Provinces, KwaZulu-Natal and the Northern Provinces in South Africa, Eswatini and the Inhaca Islands of Mozambique.References:
