The concept of establishing a botanical garden affiliated with the
University of Zagreb's Faculty of Philosophy’s Botanical and Physiological Institute was originally proposed by Professor Bohuslav Jiruš, the first botany lecturer at the University of Zagreb. It was his successor, Professor Antun Heinz, who brought the plan to life, founding the garden in 1889. Following a year-long tour of European botanical gardens, Professor Heinz—assisted by head gardener Viteslav Durhanek—crafted the master plan that would shape the garden’s future layout. Construction began in 1890, and by 1892 the first planting was underway. The vegetation was arranged not only with taxonomic relationships in mind (according to phylogenetic principles), but also with a strong emphasis on visual harmony. The majority of the space was designed in a naturalistic, English landscape style, featuring informal clusters of
trees and shrubs, winding paths, and an organic layout. In contrast, the floral parterre near the greenhouse adhered to a strict symmetrical layout, following the more formal French aesthetic. Beyond the greenery, various structures were added over time: a greenhouse and gardener’s residence appeared early on, followed by a pavilion, public restroom, ornamental ponds, and fountains. One notable milestone came in 1908 with the garden’s first official plant-collecting expedition. The team gathered 128 native plant species from regions near Zagreb,
Samobor, and
Gorski Kotar. By the early 20th century, only a decade after its founding, the Botanical Garden had already evolved into a diverse and meticulously maintained haven, praised in the writings of Professor Heinz for both its scientific value and its beauty. ==Botanical garden==
