Na privlačnost slobodnog prostora kod njegovih korisnika u velikoj mjeri utječe i izbor bilja. Cilj našeg istraživanja je bio utvrditi koje parkovne biljke su kod korisnika više a koje manje omiljene. Podatke o tome prikupili smo primjenom metoda eksperimentalne estetike. Anketirali smo ljude obaju spolova, različite starosti kao i poziva. Sastavili smo reprezentativni odabir parkovnog bilja i anketirane osobe zamolili da ih svrstaju prema njihovoj omiljenosti. Rezultati su pokazali veliku usuglašenost ispitanika u pogledu najviše i najmanje omiljene vrste uz inače prilično veliku variabilnost mišljenja.The choice of plants for open spaces greatly contributes to the attraction for their users. The aim of our research was to establish which plants the poeple prefer. The relevant data were obtained by the methods of experimental aesthetics. Both male and female persons of different age and occupation were interviewed. A representative selection of outdoor ornamental plants was made and the people interviewed were asked to classify them according to their preferences. The results showed a great harmony of the interviewees on the choice of the most favoured and the least favoured plant at otherwise a rather high variability of opinion
