The Foxtail Fern (Asparagus densiflorus ‘Myers’) is not a true fern but a member of the asparagus family (Asparagaceae). Its unique, plume-like stems are actually modified branches called cladodes. This evergreen perennial is prized for its architectural form, featuring upright, symmetrical spears densely packed with soft, needle-like foliage. It thrives in the warm, humid climate of the Southern US, performing best in USDA hardiness zones 9-11. It is moderately drought-tolerant once established but appreciates consistent moisture, and it prefers well-draining soil to prevent root rot. While it tolerates full sun, it often excels in partial shade, especially in the hottest southern regions, where it benefits from protection from the intense afternoon sun.
From a design perspective, the Foxtail Fern's most significant contribution is its striking texture. Its dense, cylindrical form provides a soft, fluffy visual and tactile contrast to plants with broader leaves or different growth habits. Utilize this characteristic by planting it alongside large-leaved plants like hostas, elephant ears (Colocasia), or caladiums. The fine texture of the fern plays against the boldness of these leaves, creating dynamic interest. Its strong, upright shape also makes it an excellent candidate for a singular focal point. A single, well-maintained Foxtail Fern in a decorative container can anchor a patio, flank an entranceway, or serve as a centerpiece in a garden bed, drawing the eye with its perfect symmetry and vibrant green color.
The plant's vibrant, light to medium green foliage serves as a brilliant foil for a wide range of flower colors. For a classic southern look, pair it with blooms in hot hues. The green foliage makes the reds, oranges, and bright pinks of plants like lantana, pentas, or bougainvillea truly pop. Conversely, for a cooler, more serene palette, combine Foxtail Ferns with white-flowering impatiens, blue plumbago, or lavender. Its evergreen nature ensures it provides a constant backdrop of color, even when seasonal flowers are not in bloom. It also complements other foliage plants beautifully, such as the silvery leaves of Dusty Miller or the purple hues of Persian Shield (Strobilanthes dyerianus).
The growth habit and structure of the Foxtail Fern lend it to various functional roles in the landscape. Its mounding, tuberous root system makes it an effective and interesting groundcover for partial shade areas, helping to suppress weeds. It is exceptionally well-suited for container gardening, either as a thriller element in mixed combinations or as a standalone specimen. Furthermore, its upright form and tolerance for pruning make it a fantastic choice for low, informal edging along pathways or garden borders. It can define a space without creating a solid, imposing barrier, maintaining a soft and inviting feel. In rock gardens, its organic forms provide a softening effect against the hardscape of stones and boulders.
