Asparagus densiflorus (among several species colloquially called asparagus ferns; no relation to actual ferns), or the foxtail fern (asparagus) or plume fern, is a variable, evergreen-perennial plant related to cultivated, edible asparagus.

Contents

It is native to southern Africa, from Mozambique to South Africa, but is widely cultivated. [1]

Foxtail asparagus is part of a group of similar-looking and related Asparagus species native to Africa, including Asparagus aethiopicus ("Sprenger's asparagus"), A. confertus and A. krebsianus . [2]

A. densiflorus has been occasionally confused with A. aethiopicus —a different, spikier, more rambling and pendant species [3] [4] [5] —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. [6] [3] Furthermore, the species known as A. densiflorus var. 'Myersii' 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 (Joshua trees).

Distribution

Asparagus densiflorus is native to the Cape Provinces, KwaZulu-Natal and the Northern Provinces in South Africa, Eswatini (Swaziland) and the Inhaca Islands of Mozambique. [7]

Cultivation

As it cannot tolerate frost, in temperate regions A.densiflorus is usually grown under glass. Numerous cultivars have been developed, of which the compact form 'Myersii' has gained the Royal Horticultural Society's Award of Garden Merit. [8] Its dense 50 cm plumes of foliage are especially valued in flower arranging.

<i>Freesia</i> Genus of flowering plants

Freesia is a genus of herbaceous perennial flowering plants in the family Iridaceae, first described as a genus in 1866 by Christian Friedrich Ecklon (1886) and named after the German botanist and medical practitioner, Friedrich Freese (1795-1876). It is native to the eastern side of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Species of the former genus Anomatheca are now included in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of a number of Freesia species. Some other species are also grown as ornamental plants.

<i>Asparagus</i> (genus) Genus of flowering plants

Asparagus is a genus of flowering plants in the family Asparagaceae, subfamily Asparagoideae. It comprises up to 300 species. Most are evergreen long-lived perennial plants growing from the understory as lianas, bushes or climbing plants. The best-known species is the edible Asparagus officinalis, commonly referred to as just asparagus. Some other members of the genus, such as Asparagus densiflorus, are grown as ornamental plants.

<i>Strelitzia reginae</i> Species of flowering plant

Strelitzia reginae, commonly known as the crane flower, bird of paradise, or isigude in Nguni, is a species of flowering plant native to the Cape Provinces and KwaZulu-Natal in South Africa. An evergreen perennial, it is widely cultivated for its dramatic flowers. In temperate areas it is a popular houseplant.

<i>Osmunda regalis</i> Species of fern

Osmunda regalis, or royal fern, is a species of deciduous fern, native to Europe, Africa and Asia, growing in woodland bogs and on the banks of streams. The species is sometimes known as flowering fern due to the appearance of its fertile fronds.

<i>Plectranthus verticillatus</i> Species of flowering plant

<i>Eucomis comosa</i> Species of flowering plant

Eucomis comosa, the pineapple flower, pineapple lily or wine eucomis, is a species of flowering plant in the asparagus family Asparagaceae. A deciduous bulbous perennial used as an ornamental plant, it is endemic to South Africa. The white to purple flowers appear in summer and are arranged in a spike (raceme), topped by a "head" of green leaflike bracts.

<i>Asparagus aethiopicus</i> Species of flowering plant

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.

<i>Gladiolus angustus</i> Species of flowering plant

<i>Eucomis vandermerwei</i> Species of flowering plant

Eucomis vandermerwei is a South African bulbous perennial flowering plant, a member of the asparagus family, and like other members of Eucomis is commonly known as pineapple lily for its superficial resemblance to that plant, although not closely related to it. This species is one of the smallest in the genus, and is native to a high-rainfall region of western Mpumalanga in South Africa. The dense rosette of leaves, either prostrate or ascending, is heavily blotched with purple, and the leaf-edges are markedly crisped or wavy. The star-shaped burgundy flowers appear in midsummer, and are borne on a spike (raceme) topped by a "head" of leafy bracts.
