Asparagus fern, Asparagus densiflorus

 

Asparagus fern is a sprawling shrub native to coastal southeastern South Africa. Despite the common name, it is not a true fern, but is in the asparagus family (Asparagaceae) or the lily family (Liliaceae, which includes plants such as amaryllis, daylilies, hosta, and tulips) depending on the classification system used. It is in the genus Asparagus, which includes the edible A. officinalis, along with about 300 other species. The exact classification of this species is a bit confused, with most references to Asparagus densiflorus, but the names A. aethiopicus, A. sprengeri, and Protasparagus densiflorus are also used as well by some.

This tender evergreen perennial with bright green, ferny foliage is commonly used as an outdoor ornamental plant or houseplant. In mild climates, it is planted outdoors as a groundcover or in containers. It is hardy in zones 9-11 but the roots will often survive to zone 7 if protected. In more temperate climates, it is used as a seasonal annual or container plant. In its native habitat, asparagus fern is found in shady, sandy sites, including coastal dunes, open rocky places and woods. Where it has escaped from cultivation, it is generally found along shady roadsides and invading woodlands or rainforests where it displaces native vegetation and prevents native species from reestablishing. It is considered an invasive weed in some locations, including Florida, Texas and Hawaii in the US.

Asparagus fern produces long, upright or trailing, branching stems sparsely covered with sharp, stiff spines in the axils. The rounded stems, up to 6 feet long, are green to brown in color and have a shallow indentation along their length. What appear to be leaves are actually leaf-like cladodes (short, flattened stems that look and function like leaves). These needle-like “leaves” arise in groups of four to eight from the nodes along the stem. The true leaves are barely visible scales near the base of the cladodes. Plants have a dense fibrous root system as well as creeping rhizomes and numerous fleshy white bulbous tubers.

Small white or pinkish-white flowers are produced in elongated clusters (racemes) along the stems from spring through fall on mature plants with sufficient light. Each flower has six tepals (3 petals and 3 sepals similar in appearance). Although fragrant, they are small enough not to be very noticeable – and plants grown in temperate climates often do not bloom. Plants are dioecious. If pollinated, female flowers are followed by small round berries up to ¼ inch in diameter. The green fruits mature to a glossy red and each contains one to three black seeds. Many birds are attracted to the fruits and are responsible for unintended seed dispersal in mild climates. The berries can cause dermatitis when in contact with skin and gastrointestinal upset if ingested and are toxic to cats and dogs.

The two most common varieties are ‘Sprengeri’ and ‘Meyeri’. The latter, commonly called foxtail asparagus fern, has more upright stems with denser foliage, resembling a fluffy animal’s tail, radiating outwards from the center of the plant. This cultivar is especially nice as an upright focal point in the ground or a container surrounded by lower plants. It does not produce seed as readily as the species so does not have the same invasive potential in mild climates. ‘Cwebe’ has graceful, upright, arching stems and copper-colored new growth. It does best in light shade. ‘Sprengeri Nanus’ and ’Sprengeri Compacta’ are more compact forms.
