LATIN NAME: Asparagus densiflorus ‘Sprengeri’
COMMON NAME: Sprenger’s Asparagus Fern
Plant Profile
Sprenger’s Asparagus Fern (Asparagus densiflorus ‘Sprengeri’) is an arching perennial of the asparagus family (Asparagaceae), a garden form of a South African species. It sends out long, scrambling, needle-clad stems 60-180 cm, with small white, fragrant flowers and bright red berries. Popular for hanging baskets and ground cover in frost-free climates, it has naturalised, sometimes invasively, in several warm countries.
Science & Biotechnology
The species features in the wider study of the Asparagus group, and its traits make it a useful subject for work on germination biology, cultivation and ornamental selection. Comparative studies between this and other Asparagus densiflorus cultivated forms have also examined how selection has shaped growth habit differences within what is fundamentally the same species. Interest from collectors and breeders has never lapsed, and good seed continues to circulate.
Uses & Benefits
Sprenger’s Asparagus Fern works well in borders, containers and dedicated beds. Sprenger’s asparagus fern is an especially popular choice for hanging baskets, window boxes and mixed container plantings, its long, gracefully trailing stems providing reliable, low-maintenance textural foliage that spills attractively over container edges. Like its upright foxtail relative, it tolerates considerable neglect and low light, making it a forgiving choice for less experienced container gardeners. It takes hold quickly and asks for no special treatment from then on.
Asparagus is a tonic food in both Western and Chinese traditions: the tender spears supply folate and the prebiotic fiber inulin, while the root, Tian Men Dong, is a classical Chinese yin-nourishing herb. Its steroidal saponins are a continuing research subject.
Growing from Seed
Starting Sprenger’s Asparagus Fern from seed is simple and satisfying. Fresh seed is best; sow it into a loose, well-drained mix and keep it warm and consistently moist. Bright, indirect light suits young plant well, and this trailing form typically develops its characteristic cascading stems once established, well suited to eventual transplanting into a hanging basket or container edge. Level a tray of loose seed compost, sow evenly, cover to about the seed’s own depth, and keep it moist in full light. Move strong seedlings into individual pots, keep them in good light, and set them out when the weather and their size agree.
Our Take
Few garden plants carry such a documented history of use as this one does. Sprenger’s Asparagus Fern is the kind of plant that rewards a permanent spot. Beginners will find it patient of imperfect technique.
