Description

Agave attenuata, commonly known as the Lion's Tail or Foxtail Agave, is a striking, architectural succulent that adds a dramatic flair to any garden or landscape. This agave is known for its unique, soft, pale green rosettes that curve upward in a gentle spiral, resembling a lion’s tail or a swan’s neck. Unlike many other agaves, it has smooth, non-spiny leaves, making it a safer choice for gardens with children or pets. In late spring or early summer, it produces a tall, creamy flower spike, further adding to its visual appeal.

Light requirements

This agave thrives in full sun but can tolerate partial shade, especially in regions with intense heat. For optimal growth and a more vibrant color, it should be placed in a spot that receives several hours of direct sunlight each day. While it can survive in shadier areas, the plant may not bloom as prolifically and could have a more elongated growth habit.

Soil preferences, including pH and drainage

Agave attenuata requires well-draining, slightly acidic to neutral soil with a pH between 6.0 and 7.5. It is particularly well-suited for sandy or gravelly soils that allow water to drain away quickly, as standing water can lead to root rot. In garden settings, amend heavy soils with sand or perlite to improve drainage. If growing in containers, use a cactus or succulent-specific potting mix for the best results.

Water needs

Agave attenuata is drought-tolerant and prefers to dry out between waterings. It’s important to water the plant thoroughly but infrequently, allowing the soil to dry completely before watering again. During the warmer months, water every two weeks or so, but reduce watering during the cooler seasons when the plant’s growth slows. Overwatering or allowing the plant to sit in waterlogged soil can lead to root rot, so make sure the plant has adequate drainage.
