About Prickly pear
Opuntia tuna, also known as Prickly Pear or Tuna Cactus, is a shrubby or arborescent cactus native to Mexico, characterized by its oval, spiny pads (cladodes) that produce yellow flowers and edible reddish fruits. It can grow quite tall, forming impressive hedges or solitary specimens. It's ideal for xeriscapes, rock gardens, or as an ornamental plant in warm, dry climates, adding an exotic and structural touch to the landscape.

Care tips
It requires full sun exposure for optimal growth and abundant flowering. Watering should be infrequent, allowing the substrate to dry out completely between waterings, especially in winter to prevent rot. Use a very well-draining substrate, specifically for cacti and succulents, with a good proportion of sand or perlite. A common mistake is overwatering, which is the main cause of death for this plant.
