Growing directions
Plant in partial shade in moist, well-drained soil; Asparagus Fern adapts remarkably well to shaded conditions and grows fastest with morning sun and afternoon shade in zone 9 — it tolerates more light than most foliage plants while also performing adequately in fairly deep shade. Asparagus densiflorus is not a true fern but a member of the asparagus family (Asparagaceae), native to southern Africa. Despite the common name, it is closely related to edible garden asparagus (A. officinalis) — the feathery, bright emerald-green foliage that makes it so popular consists of tiny flattened stems (cladodes) that function as leaves. The 'Sprengeri' cultivar produces arching, 2–3-foot stems clothed in fine needlelike cladodes and scarlet berries; the 'Meyeri' (Foxtail Fern) cultivar produces upright, dense, bottle-brush-shaped plumes of bright green. Both forms are outstanding for adding fine-textured, feathery foliage to shaded garden beds, container arrangements, and as groundcovers under trees. The thick, tuberous, fleshy roots store substantial water reserves, giving established plants surprising drought tolerance despite the plant's lush appearance. CAUTION: The berries are mildly toxic if ingested by children or pets. Listed as invasive in some Gulf Coast and Floridian habitats where bird-dispersed seeds colonize disturbed areas.
