About Black-spined agave
Agave macroacantha, commonly known as Mexican Maguey, is a striking succulent that forms symmetrical rosettes of stiff, distinctive blue-gray leaves with prominent dark spines. Its compact size and attractive form make it ideal for rock gardens, large pots, or as a focal point in xeriscape landscapes. It's a sculptural plant that adds an elegant desert touch to any collection.
Native range
Central and Southern Mexico
Care tips
It requires full sun to develop its optimal coloration and compact growth; insufficient light can cause its leaves to stretch. Watering should be sporadic, allowing the substrate to dry out completely between waterings, especially in winter to prevent rot. Use a very well-draining substrate, specific for cacti and succulents. A common mistake is overwatering, which is the leading cause of death for this species.
