Consolea rubescens is part of the Cactaceae family and its native range is Puerto Rico to Leeward Islands where it grows as a succulent tree in the seasonally dry tropical biome.
This is an almost spineless species with flattened cladodes and bumpy areoles. In its native environment it can reach up to 6m in height. Flowers are brightly coloured (red, orange or yellow) and they produce a showy fruit.
Genus name honours the inspector of the Palermo Botanical Garden Michelangelo Console. Specific epithet means reddening.
Light: This plant thrives in full sun. It requires at least six to eight hours of direct sunlight daily to encourage robust growth and potential flowering. When growing indoors in the UK, placing it in the brightest available window is crucial.
Water: Water sparingly. This succulent cactus stores water efficiently in its pads, so allowing the potting mix to dry out completely between waterings is vital. During the active growing season (spring and summer), water thoroughly, ensuring all excess moisture drains away. Significantly reduce watering in autumn and winter when the plant is dormant. Overwatering is a frequent cause of rot.
Soil: A very well-draining potting mix is essential. A specialist cactus or succulent mix is ideal. This type of mix will help prevent water accumulation, which is crucial for the plant's health, particularly in the UK's often damp climate.
Fertilising: This plant is not a heavy feeder. During the growing season (spring and summer), a diluted liquid fertiliser formulated for cacti and succulents can be applied monthly. Reduce or stop fertilising during the dormant period.
Temperature: Opuntia consolea prefers warm temperatures and is not reliably frost-tolerant. It thrives in warm, dry conditions and should be protected from temperatures below 0°C for any extended period. If grown outdoors in the UK, it should be brought indoors before temperatures drop.
Humidity: Average household humidity levels are sufficient. This plant prefers dry air and does not require high humidity.
Growth Habit: It typically grows upright, forming a tree-like or sprawling structure with flattened, paddle-shaped segments. It can become quite tall over time.
Toxicity: Opuntia species are generally considered non-toxic to humans and pets in terms of chemical compounds. However, the plant possesses fine, barbed hairs called glochids, which can detach easily and cause significant irritation, discomfort, and inflammation if they get into the skin or are ingested. Handle with care, and keep it out of reach of children and animals to prevent physical injury from spines and glochids
