The construction of the Botanical Garden in Zagreb begun in 1889, and its founder was prof. A. Heinz. Of the 4.7 hectares of the Botanical Garden’s total area, the greatest part is occupied by the arboretum, developed in the style of the English landscape garden, in which we woody plants (trees and shrubs) from various parts of the world are grown.
The flower parterre with decorative herbaceous plants (annuals and perennials) and roses, in the western part of the Garden near the glasshouses, is constructed in the French style characterised by strict geometrical lines. Indigenous plant species (representatives of the flora of Croatia) are grown in groups planned according to plant geography (rock gardens).
Tropical and subtropical plants and plants needed for research work are grown in the greenhouses (a total of 14).
Marsh plants can be seen in the artificial lakes and pools on the parterre. In the systematic field in the southeast part of the Garden there are plants meant for students and for university lectures.
More detailed info about the garden can be found on their official web page
The cache is hidden outside of the park, but I strongly invite you to visit the beautiful park (there is another cache inside). I haven't been inside in ages, so I was really pleasantly surprised when I saw how well maintained it is. Fantastic flowers, not one piece of garbage, broken branch or dry leaf. Several universities are close by, so you can find occasional couples exchanging kisses and romantic words on many benches around the park. The opening hours are a bit odd, the park is open only from April 1st to November 1st, so it is closed during the winter. The weekly opening hours are the following:
The entrance is FREE!!
