Sickle Thorn Fern

Sickle Thorn Fern (Asparagus falcatus)

Sickle Thorn Fern (Asparagus falcatus) is a vigorous, twining evergreen vine or scrambling shrub known for its arching stems, glossy foliage, and tough, wiry structure. Despite its common name, it is not a true fern but shares a delicate, feathery appearance. Popular for both indoor and outdoor use, this bold species adds lush, tropical texture to hanging baskets, trellises, or shaded garden beds.

Distinctive Features

Asparagus falcatus produces curved, flattened cladodes that resemble leaves but are actually modified stems, giving the plant its soft, fern-like appearance. The stems are strong and may develop small, sharp thorns. Mature plants can grow several feet long, making them ideal for training on supports or cascading from elevated planters. In warm climates, it may also produce small white flowers followed by red berries.

Growing Conditions

• Light: Bright, indirect light to partial shade
• Soil: Well-drained potting mix or rich garden soil
• Water: Moderate; allow top layer of soil to dry between waterings
• Humidity: Tolerates dry air but benefits from occasional misting
• Temperature: Prefers 60 to 80 degrees Fahrenheit; protect from frost

Ideal Uses

• Focal Point: Dramatic, arching foliage brings movement and softness to plantings
• Hanging Baskets: Cascades beautifully in suspended containers
