The Foxtail Agave (Agave attenuata), also known as the Lion’s Tail or Swan’s Neck Agave, is a stunning, spineless agave known for its smooth, blue-green leaves that form a rosette. Unlike other agave varieties, it has no sharp spines, making it a popular choice for ornamental landscapes and container gardening. Its name comes from its gracefully arching flower spike, which resembles a foxtail.
