Kirstenbosch National Botanical Garden, South Africa
Nestled against the eastern slopes of Cape Town’s Table Mountain, Kirstenbosch stands as the only botanical garden in the world within a UNESCO World Heritage Site. This 36-hectare masterpiece showcases the extraordinary diversity of the Cape Floral Kingdom – the smallest yet richest of Earth’s six floral kingdoms.

The garden’s Centenary Tree Canopy Walkway offers visitors a bird’s-eye view across the garden and surrounding mountains. This curving steel and timber bridge winds through the trees, creating a sensation of floating above the forest floor.

Between November and April, the summer concert series transforms the garden’s rolling lawns into a natural amphitheatre, where local musicians perform against Table Mountain’s sunset-washed backdrop.

Singapore Botanic Gardens, Singapore
These 162-year-old gardens have evolved from colonial-era experimental plantations to one of the world’s preeminent orchid research centres.

The National Orchid Garden houses over 1,000 species and 2,000 hybrids, including Singapore’s national flower, the Vanda Miss Joaquim. The garden’s orchid breeding programme has even created over 500 new varieties!

The gardens’ Heritage Trees collection includes specimens older than the garden itself, while the six-hectare rainforest patch contains more than 300 species. The Symphony Lake becomes a magical setting for weekend concerts, where music drifts across the water as families picnic on manicured lawns.

Jardín Botánico de Medellín, Colombia
Medellín’s transformation is perfectly encapsulated in its botanical garden. This 14-hectare urban oasis houses over 4,500 flowers and 139 bird species in what was once among the world’s most dangerous cities.

The garden’s iconic Orchideorama – a wooden mesh canopy resembling giant honeycombs or flowers – provides shelter for the orchid collection while harvesting rainwater.

The butterfly house flutters with Colombia’s extraordinarily diverse lepidoptera, while the desert garden showcases the surprising diversity of the country’s arid regions. The garden also hosts the annual Feria de las Flores in August, where spectacular flower arrangements and cultural performances celebrate the region’s horticultural heritage.

Koishikawa Botanical Garden, Japan
Tokyo’s oldest botanical garden offers a peaceful counterpoint to the megacity’s frenetic energy. Established in 1684 as a medicinal herb garden, this 16-hectare living museum now houses over 4,000 plant species under the management of the University of Tokyo.

Unlike Japan’s more famous ornamental gardens, Koishikawa’s focus remains scientific, yet its beauty shines through its classical Japanese landscape design.

Meticulously maintained moss garden creates a carpet of velvet green, particularly enchanting after rain, while plum groves explode with blossoms in late February, announcing the arrival of spring before the more famous cherry trees. The garden’s medicinal herb garden continues its original purpose, displaying plants used in traditional Japanese medicine for centuries.
