Are Asparagus Fern and Foxtail Fern the Same?

Garden enthusiasts and indoor plant lovers, have you ever found yourself pondering whether the asparagus fern and foxtail fern are the same plant?

It’s a question we’re asked frequently at LeafWise Plant Care. These two plants share more than just a part of their names; they share a confusing similarity that often leads to mix-ups.

However, the short answer to this botanical conundrum is no, the asparagus fern and foxtail fern are not the same. Let’s dive deeper into the distinguishing aspects of these fern-like plants to understand why they’re often confused for one another and how to tell them apart.

Asparagus Fern vs Foxtail Fern: Distinguishing Features

Origins and Family Ties

Both the asparagus fern and foxtail fern belong to the Asparagus genus, which explains the first part of their botanical names:

  • Asparagus Fern: Asparagus setaceus
  • Foxtail Fern: Asparagus densiflorus

Despite their fern-like appearance, neither plant is a true fern. Instead, they’re flowering plants that have adopted a ferny façade.

The confusion between the two often stems from their similar appearance and shared family, but they are distinctly different species within the same genus.

Leafy Illusions: Understanding Their Foliage

A key identifier that sets the asparagus fern (Asparagus setaceus) apart from the foxtail fern (Asparagus densiflorus) is their foliage.

The asparagus fern is known for its delicate, feathery leaves that are actually modified stems called cladodes. These give the plant a soft, airy texture.

The foxtail fern boasts denser, bushier growth that resembles a fox’s tail—hence the name. Its stems are packed closely together, creating a striking, sculptural effect that’s more robust than the delicate asparagus fern.

Growth Habits and Environment

Both plants thrive in warm, humid environments and can be grown outdoors in USDA hardiness zones 9 to 11. However, their growth habits further highlight their differences.

Asparagus ferns prefer shaded areas where their light foliage can spread and cascade beautifully, making them perfect for hanging baskets or as understory plants in garden beds.

Foxtail ferns, with their sturdier stems, are more adaptable to direct sunlight and can be used as focal points in garden design or as statement houseplants. Their dense, upright growth habit makes them a favorite for adding texture and greenery to spaces.

Care and Maintenance: A Brief Guide

Caring for these plants requires understanding their specific needs. While both appreciate moist soil and regular watering, the asparagus fern is more drought-tolerant once established. Overwatering can lead to yellowing leaves, so allowing the soil to dry out slightly between waterings is key.

Foxtail ferns, conversely, benefit from more consistent moisture and can react negatively to dry conditions by shedding their needles. Providing a balanced, liquid fertilizer during the growing season supports their lush, green growth.
