Agave Victoria-Reginae 'Porcupine' is an easy-to-care-for succulent that adds an intriguing, architectural element to outdoor space. This showy evergreen's long, red-tinted spines rise up like a porcupine's quills, giving the plant a unique, eye-catching look. It's a great choice for a succulent garden or as a focal point in a rock garden. To plant, choose a location in full sun with well-draining soil. Dig a shallow hole twice as wide as the root ball and mix in some organic compost with the existing soil. Position the root ball in the hole and fill in with soil. Water deeply to help the roots settle. Then mulch around the base of the plant to help retain moisture and control weeds.
