Rumah Kaca Kaktus (Cactus Greenhouse), Bali Botanic Garden

Kebun Raya Eka Karya Bali was officially opened on 15 July 1959 on 50 hectares near Bedugul; it now covers 157.5. The environmental news site Mongabay credits the initiative to Kusnoto Setyodiwiryo and I Made Taman and notes that it was the first Indonesian botanic garden created outside Java; its name, "Eka Karya", means "first creation". Long attached to the Indonesian Institute of Sciences (LIPI), it now comes under the National Research and Innovation Agency (BRIN).

The sources consulted do not date the building of the cactus greenhouse. They do, however, record the landslides of 27 December 2016 and 9 February 2017: after five hours of rain, flows of mud and stones from Tapak Hill destroyed seven bridges and carried away dozens of specimens, among them orchids brought back from expeditions to Papua and within Bali. A monument of stone pyramids, the Svaha Bumi, recalls the event at the entrance to the greenhouse. After a period of closure, the greenhouse reopened with a new look on 1 January 2023.

The cactus greenhouse covers about 500 m², opposite the orchid garden. Its purpose is climatic: at Bedugul, between 1,250 and 1,450 m above sea level, days range from 17 to 25 °C, nights from 10 to 15 °C, and air humidity stays between 70 and 90 per cent. The greenhouse is therefore designed to reduce humidity around plants adapted to dry habitats, and it is built on a raised construction.

The interior imitates the natural habitat of these species: mounds of coral rock form a landscape of hills and arid ground. A dryland flora is thus staged in the middle of a damp mountain garden; the garden's own page describes this greenhouse as one of those with the finest display.

According to BRIN's survey of October 2022, the greenhouse holds at least 916 specimens belonging to 98 species and eight families of cacti and succulents; the garden's own page counts 47 genera. The plants come from Bali, but also from Mexico, Germany, New Zealand and Argentina. Among them are the golden barrel cactus (Echinocactus grusonii), a globular species that grows to about 1 m, and Cleistocactus micropetalus, with club-shaped stems about 2 m tall, alongside sansevierias and aloes (Aloe vera).

The garden also keeps one of the largest begonia collections in the world, with around a hundred species, as well as more than 300 species of orchids.

The garden lies at Bedugul, in Tabanan regency, about 90 minutes' drive north of Denpasar, with views of Lake Bratan and the Ulun Danu temple. The cactus greenhouse faces the orchid garden and combines with the begonia collection, the fern garden (188 species) and the bamboo garden (87 species). The garden is home to at least 79 bird species; it received 350,000 visitors in 2011, 10,000 of them from abroad. At the greenhouse entrance, the Svaha Bumi monument recalls the landslides of 2016–2017; a giant ficus stands on the slopes of Tapak Hill, and three Hindu temples can be reached within the garden grounds.
