Opuntia macrocentra ‘Negra’ is a dramatic and highly decorative prickly pear cactus, prized for its rich, deep colouring and striking architectural form. Native to the arid regions of the southwestern United States and northern Mexico, this variety stands out for its flattened pads, which range in colour from dusky blue-green to deep purple or even near-black in strong sunlight. The intensity of the colour deepens with light exposure and cooler temperatures, giving this cactus a bold and ever-changing appearance.
The pads are beautifully contrasted by long, dark spines, often reddish-brown or black, which add to its striking visual impact. In late spring or early summer, mature plants may produce vivid yellow flowers with orange to red centres, followed by small, ornamental fruits. Its combination of sculptural shape, dramatic tones, and seasonal colour make Opuntia macrocentra ‘Negra’ a superb focal point for any plant collection, both indoors and out.
This variety thrives in bright, direct sunlight and requires a free-draining cactus compost to prevent waterlogging. Water sparingly, allowing the soil to dry completely between waterings, and reduce watering over winter when growth slows. It is best kept in a sunny windowsill, conservatory, or greenhouse in the UK, and can be placed outdoors during warmer months if sheltered from excessive rain.
Perfect for garden centres and houseplant shops, Opuntia macrocentra ‘Negra’ offers customers a rare and visually captivating cactus that combines easy care with exceptional ornamental value. Its rich, dark tones and dramatic silhouette make it a must-have for collectors and anyone seeking a truly unique desert plant.
