Melocactus Broadwayi

The Melocactus broadwayi is a fascinating species of the genus Melocactus, native to the island of Trinidad. It is distinguished by its modest size, bright green globular body, and its impressive orange to reddish cephalium. Like its relatives, it follows a specific growth cycle: a vegetative phase during which the body develops, followed by cephalium formation marking maturity.

This cactus remains relatively small, with an average diameter of 10 to 12 cm. It has between 10 and 14 slightly rounded ribs, adorned with fine areoles bearing white to light brown spines arranged in a star pattern. The contrast between the green body and the intense orange cephalium makes it a remarkable collector’s specimen.

The cephalium, dense and cylindrical, is composed of white wool mixed with red bristles. It regularly produces small pink to mauve flowers in summer, followed by decorative cylindrical pink fruits.

The Melocactus Broadwayi is endemic to the island of Trinidad in the Caribbean. It naturally grows in dry, rocky areas exposed to direct sunlight, within a hot and humid tropical climate with marked seasons.
🌞 Direct sunlight essential: Place the cactus in full sun to stimulate cephalium development and maintain a compact form.

🌤️ Indoor cultivation: South-facing window or full-spectrum artificial lighting.

☁️ Low light: Causes etiolation and prevents flowering.
🌱 Warm season (April to September): Moderate watering every 15–20 days. The substrate must dry completely.

🍂 Cool season (October to March): Very infrequent watering, or none if kept dry.

⚠️ Tip: Excess moisture is the main enemy. Proper drainage is essential to avoid root diseases.
🌡️ Ideal range: 22°C to 30°C.

❄️ Lower limit: Never below 12°C. Frost is not tolerated.

🏠 Winter advice: Place in a bright, temperate room and avoid humid environments.
🪴 Draining and poor soil: Use a mix of 50% cactus substrate and 50% mineral components such as gravel or pumice.

🧪 Important: Never use pure universal potting soil, which is too compact for this species.
🌸 Appearance: Once the cephalium is well developed.

🎨 Flowers: Small, pink to mauve, discreet but regular.

🍓 Fruits: Small, cylindrical, pink. They may remain visible for several days and are sometimes edible.
