In detail
What's here
The garden is divided into thematic zones: an arboretum, a systematic plant collection arranged by botanical classification, a rockery, and a Mediterranean plant section. The collection spans flora from all continents – from alpine grasses to subtropical shrubs. Each plant is labelled with its Latin and Slovenian name. The tropical glasshouse, built for the garden's 200th anniversary in 2010, contains over 380 tropical species.
Paved paths wind through the grounds with benches placed along them. The atmosphere is quiet, with few visitors even in season – this is a local retreat rather than a tourist hotspot. Near the entrance, the Primula Teahouse serves drinks and homemade pastries.
In spring (March–May), tulips, magnolias, and cherry trees bloom. Summer brings the glasshouse to its peak. Autumn colours the foliage golden with almost no crowds. In winter the garden stays open, but the glasshouse becomes the main draw.

History
Past & present
The botanical garden was founded in 1810 by botanist Franc Hladnik when Ljubljana served as the capital of Napoleon's Illyrian Provinces. Originally created as a repository for native flora and a teaching ground, the collection grew from a few hundred to 4,500 species over two centuries. The garden now cooperates with more than 270 botanical gardens worldwide.
In 1974, part of the territory was lost to railway construction. The tropical glasshouse opened in 2010 for the bicentenary. In 2018, the garden received BGCI international accreditation – one of the first seven botanical gardens in the world to do so. In 2024, a public campaign was launched to preserve the garden amid plans for a second railway track along its boundary.
