The botanical garden in Troja is situated near the Prague ZOO. It is open throughout the year and in my opinion is the prettiest in spring and autumn.
The outside exposition is a large area of 25 hectares in total. It consists of several interesting parts including eg. an ornamental garden, a Mediterranean flora area, a vineyard (with a wine cellar), a peat bog with a small lake, a peony meadow and much more – it depends on what you like and what you are in the mood for :-).
As the season changes, there are also topical exhibitions – recently I visited a nice and colorful pumpkin exhibition and I’m already looking forward to the traditional spring bonsai exhibition which takes place in the beautiful and peaceful Japanese garden.
