How to Grow Foxtail Fern

Growing Foxtail Fern successfully requires well-drained soil, moderate watering, and bright light ranging from full sun to partial shade. Foxtail Fern (Asparagus densiflorus ‘Myersii’) is an ornamental perennial grown for its dense, upright plumes of needle-like foliage. Gardeners researching how to grow Foxtail Fern should focus on providing soil that drains well and maintaining consistent but moderate moisture. Under proper Foxtail Fern growing conditions, plants develop dense clumps of upright stems that provide year-round texture in landscapes and containers.

Plant Name

Foxtail Fern

Scientific Name

Asparagus densiflorus ‘Myersii’

Overview

Foxtail Fern is a durable ornamental plant widely used for its distinctive plume-like foliage. Although commonly called a fern, it is actually a member of the asparagus family. The plant forms dense clumps that produce upright stems resembling soft bottlebrushes.

Foxtail Fern care is relatively simple when plants receive well-drained soil and moderate watering. Once established, the plant tolerates a range of conditions and maintains consistent structure.

Plant Description

Foxtail Fern grows as a clumping perennial with upright stems that emerge from a central crown. The stems are covered in dense, needle-like branchlets that give the plant a soft, feathery appearance. As stems mature, they may arch slightly outward.

Plants gradually expand through underground storage roots.

Flower Description

Small white flowers may appear along the stems during warm weather. These flowers are typically small and not the primary ornamental feature.

In some cases, flowers may be followed by small red berries.

Foliage Description

The plant produces dense, needle-like foliage arranged along upright stems. The foliage is bright green and soft in appearance.

These upright plumes create the distinctive “foxtail” structure that gives the plant its common name.

Deciduous or Evergreen

Evergreen in warm climates. In cooler climates, foliage may be damaged by freezing temperatures but regrows from the root system.

USDA Grow Zones

Zones 9–11 outdoors. In cooler regions, it is often grown in containers or as a seasonal plant.

Mature Height and Width

18–24 inches tall
24–36 inches wide

Growth Habit

Clumping perennial with upright to slightly arching plume-like stems.

Native Range

The species Asparagus densiflorus is native to southern Africa.

Sun Exposure

Foxtail Fern grows well in full sun to partial shade. Plants may produce denser foliage when grown with some protection from intense afternoon sun.

Bright light supports healthy growth.

Soil Requirements

Foxtail Fern growing conditions require soil that drains well. The plant adapts to sandy, loamy, or organic-rich soils.

Soil that remains excessively wet may lead to root problems.

Water Requirements

Provide moderate watering during active growth. Soil should dry slightly between watering cycles.

Once established, the plant tolerates moderate dry conditions.

Fertilizing

Light fertilization during the growing season supports steady growth. A balanced fertilizer applied periodically is usually sufficient.

Avoid excessive fertilization.

Pruning and Maintenance

Occasional pruning may remove damaged or aging stems. Cutting back older stems encourages new growth from the crown.

Maintenance is minimal once the plant is established.

Pests and Problems

Foxtail Fern is generally resistant to major pest issues. Spider mites, scale insects, or mealybugs may occasionally appear.

Regular inspection helps prevent infestations.

Disease Resistance

When planted in well-drained soil with good air circulation, the plant shows good resistance to disease.

Heat Tolerance

Foxtail Fern tolerates warm temperatures and performs well in hot summer conditions when soil moisture is maintained.

Cold Tolerance

The plant is sensitive to freezing temperatures. Severe frost may damage foliage but plants can regrow from the root system if roots remain protected.

Landscape Uses

Foxtail Fern is commonly used in borders, container plantings, and foundation beds. The upright plumes provide strong texture in mixed plantings.

The plant is also frequently used in patio containers and decorative planters.

Container Growing

Foxtail Fern grows well in containers using well-drained potting soil. Containers should have drainage holes to prevent water accumulation.

Container-grown plants may require more frequent watering during warm weather.

Companion Plants

Foxtail Fern pairs well with plants that share similar growing conditions, including:

Hibiscus
Lantana
Croton
Coleus
Cordyline

These plants complement its foliage texture and structure.

Wildlife Value

The small flowers may attract pollinators such as bees. Birds may occasionally feed on the berries when present.

Is It Edible or Medicinal

Foxtail Fern is grown primarily for ornamental use. The berries are considered toxic if ingested and should not be consumed.

Why Foxtail Fern Turns Yellow

Yellowing foliage may occur when plants receive excessive water or when soil drainage is poor. Improving drainage and adjusting watering practices can help restore plant health.

Why Foxtail Fern Gets Sparse

Sparse growth may occur when plants receive insufficient light or when older stems decline naturally. Removing aging stems encourages new growth.

Why Foxtail Fern Dies or Declines

Root rot caused by overly wet soil is the most common cause of plant decline. Well-drained soil helps prevent this problem.

Why Foxtail Fern Falls Over

Stems may arch or lean as they mature, particularly when plants grow in shaded locations. Adequate light supports more upright growth.
