Tucked within the Exotic Garden of Monaco, the Botanical Centre houses one of the world’s most remarkable collections of cacti and succulents…
Since its founding in 1960, the greenhouses have preserved rare species from across the globe, including the aloe dichotoma, of which only about 100 remain worldwide, and the distinctive “hatted” cactus. In total, the centre cares for around 10,500 plants, with 10,000 in pots and 500 in open ground.
These species, many of which cannot survive outdoors in Monaco’s climate, are protected in specially designed shelters and greenhouses. Approximately 90% are safeguarded under international conservation regulations, and staff carry out controlled pollination to preserve pure strains. Seeds are catalogued in an index, which is shared with botanical gardens worldwide, contributing to global plant conservation.
While Monaco’s current summer heatwave can be dangerous for people, it poses no threat to these xérophytes, which thrive in hot, dry conditions and require little water. In their native habitats, some survive for years on nothing more than morning dew. Nevertheless, under greenhouse care, they receive carefully measured watering to ensure their continued health.
The Exotic Garden is scheduled to reopen in October, but visitors don’t have to wait to enjoy this unique collection. The Botanical Centre’s greenhouses are open free of charge from Tuesday to Saturday, 8:30 a.m. to 4 p.m., offering a rare opportunity to explore a living desert oasis in the heart of Monaco.
