Overview

Asparagus densiflorus 'Myersii' is the foxtail fern, growing 18–24 inches (45–60 cm) tall and 24–36 inches (60–90 cm) wide. Dense cylindrical plumes of bright green needle-like cladodes (modified stems that function as leaves) — each stem 12–18 inches (30–45 cm) long resembles a foxtail shape. Not a true fern — in the asparagus family (Asparagaceae), related to edible asparagus (A. officinalis). The 'Myersii' form has upright cylindrical plumes vs. the loose cascading form of A. densiflorus 'Sprengeri'. Thick tuberous roots store water — drought-tolerant once established. Small fragrant white to pale pink flowers in summer followed by bright red berries 0.25 inch (6 mm) in fall — the berries are mildly toxic. Birds consume the berries and spread seeds; the species is invasive via bird-dispersed seed in frost-free zones. Contact with the foliage may cause dermatitis in sensitive individuals. Native to South Africa. Deer-resistant. Zones 9–11 outdoors; grown as a houseplant or seasonal container plant in cold zones. Full sun to partial shade. Well-draining soil. The tuberous root mass can crack pots when rootbound.

Native Range

Asparagus densiflorus is native to South Africa.

Suggested Uses

Grown in containers of 2–3 gallons (8–12 liters) in full sun to partial shade. Outdoors year-round in zones 9–11; seasonal outdoor/indoor in cold zones. The upright foxtail plume form suits urns, planters, and mixed containers. Mildly toxic berries. Contact dermatitis possible.

How to Identify

Identified by dense cylindrical foxtail-shaped bright green plumes on upright stems. Not a true fern — in the asparagus family (Asparagaceae). Distinguished from A. densiflorus 'Sprengeri' (cascading, loose form) by the dense, upright cylindrical plume shape. Bright red berries in fall.

Care Guide

Full sun to partial shade. Drought-tolerant (tuberous roots store water). Well-draining soil. Not a true fern — asparagus family. Mildly toxic berries. Contact dermatitis possible. Invasive via bird-spread seed in frost-free zones. Zones 9–11 outdoors.

Pruning

Remove browned or yellowed stems at the base. Divide rootbound plants — the tuberous root mass can crack containers. Cut all growth to 2 inches (5 cm) in spring for rejuvenation.
