From landfill to landmark
Until 1983, this 40 m (131 ft) hill was the city's dump, and work to remake it as a botanic garden began in 1996. The public opening finally came in 2014 after years of planting, gas extraction, path building, and slope stabilization. Once you know that backstory, the calm of the garden feels even stranger and better earned.
Island worlds instead of generic beds
The collection is organized around island and coastal biogeography rather than generic ornamental planting. More than 3,000 plant species and over 600 palm species are spread through sections that evoke the Caribbean, Madagascar, New Caledonia, New Guinea, and the Canary Islands. That is why the walk feels like moving between small climates, not strolling past repeated flowerbeds.
The octagon is the garden's showpiece
The jewel of Palmetum is the octagonal humid house, a semi-enclosed space of rocks, streams, and waterfalls on two levels. Outside it, lakes, Caribbean-style cascades, and sea viewpoints keep shifting the mood between sheltered jungle and open skyline. Few city gardens make that contrast this quickly.
Even repeat visits have something new
This is not a frozen collection. In December 2024, a new Papua New Guinea zone added about 1,600 m² (17,220 ft²), roughly 100 new plantings, around 50 species, a lake, and a bird hide. If you already know the older loop, that fresh corner gives you a real reason to come back.
