Overview
The foxtail fern grows dense, upright, plume-like fronds that really do look like bushy fox tails - a bold, drought-tough foliage plant. Like its relative the asparagus fern, it is NOT a true fern (it's an asparagus) and it IS toxic to pets, berries included. (Asparagus densiflorus 'Myersii'.)
Origin & Natural Habitat
Southern Africa; a cultivar of the same species as the sprawling 'asparagus fern', selected for its dense upright plumes.
Appearance
Stiff, upright, cylindrical plumes 40-60 cm packed with fine needle-like cladodes, radiating like fox tails; small white flowers and red berries on mature plants.
Why People Grow It - Qualities & Benefits
- Bold, sculptural fox-tail plumes
- Very drought-tolerant (tuberous roots)
- Tough in ordinary rooms and patios
- Striking upright form
Care
Light: Bright indirect light to some direct sun; the brightest of the 'ferns' here.
Water: Drought-tolerant thanks to water-storing tubers - water when the top dries; it forgives missed waterings better than any true fern.
Soil: Well-draining potting mix; vigorous tuberous roots become pot-bound fast.
Temperature & Humidity: 13-27°C; tolerates dry air and warmth well.
Feeding: Balanced feed monthly in the growing season.
Extra: ⚠️ TOXIC to cats and dogs (foliage irritates, red berries especially hazardous) and NOT a true fern - it's an asparagus. Also invasive in some warm regions; keep it contained and never plant it out where it can spread.
Propagation
Divide the tuberous crown; seed from berries (gloves - the sap can irritate).
Common Problems & Pests
Yellowing = too dark; pot-cracking from vigorous tubers. Very forgiving of dryness otherwise.
Toxicity & Safety
⚠️ Toxic to cats and dogs (ASPCA); berries especially hazardous. Not pet-safe. Invasive outdoors in some warm climates.
Best Suited For
- Beginners and forgiving-fern seekers
- Homes WITHOUT pets, or with the plant well out of reach
- Shade and bright-indirect spots
- Ordinary indoor rooms
FAQ
Is the foxtail fern a fern?
No - like the asparagus fern it's in the asparagus family, not a true fern; the fine plumes just look ferny.
Is it pet-safe?
No - it's toxic to cats and dogs and the berries are especially hazardous. For a pet-safe plant choose a true fern like the Boston or button fern.
