About Dagger cactus
Opuntia dejecta, commonly known as Dejected Prickly Pear or Golden Spined Prickly Pear, is a fast-growing shrubby or tree-like cactus native to the Antilles. It is characterized by its flat, bright green pads (cladodes) covered with fine, golden spines that give it a distinctive appearance. It is ideal for xeriscape gardens, rockeries, or as an ornamental plant in large pots, adding an exotic and low-maintenance touch.
Native range
Caribbean, including islands such as Cuba, Hispaniola and Puerto Rico
Care tips
It requires full sun for optimal development and abundant flowering; lack of light can lead to etiolated growth. Watering should be moderate in spring and summer, allowing the substrate to dry out completely between waterings, and almost nonexistent in winter. It prefers a very well-drained, sandy, or cactus-specific substrate to prevent waterlogging. A common mistake is overwatering, which can quickly lead to root and cladode rot, proving fatal for the plant.
