U radu se prikazuju rezultati analize hortikulturne flore kućnih vrtova Gacke doline koja je s jedne strane omeđena Velebitom, a s druge Kapelom. Istraživanje je provedeno tijekom 2018. i 2019. godine, te revidirano 2021. godine. Nasumično je izabrano 40 vrtova koji se nalaze na različitim lokalitetima Gacke doline. Na istraživanoj površini determinirane su 133 svojte u sklopu 113 rodova i 60 porodica. Brojem svojta dominiraju kritosjemenjače (129 svojta; 96,99 %) i to dvosupnice (114 svojta; 85,71 %). Od prisutnih porodica najzastupljenija je porodica Rosaceae (12,78 %), a od rodova rod Prunus (5,26 %). Prema vrsti habitusa većina svojta su grmovi (30,83 %). Veća je dominantnost vazdazelenih svojti (61 %) u odnosu na listopadne. Prema geografskom podrijetlu su brojnije alohtone vrste (58,65 %) i to podrijetlom iz Amerike (26,92 %). Svojte ukrasnog karaktera (54,14 %) zastupljenije su od utilitarnih. The paper presents the results of the analysis of the horticultural flora of the home gardens of the Gacka Valley, which is bounded on one side by Velebit and on the other by Kapela. The research was conducted in 2018 and 2019, and revised in 2021. 40 gardens located in different localities of the Gacke Valley were randomly selected. 133 taxa in 113 genera and 60 families were determined on the investigated area. The number of taxa is dominated by angiosperms (129 taxa; 96.99%) and dicotyledons (114 taxa; 85.71%). Of the families present, the Rosaceae family is the most represented (12.78%), and of the genera, the genus Prunus (5.26%). According to the type of habitus, most taxa are shrubs (30.83%). There is a greater dominance of evergreen taxa (61%) compared to deciduous taxa. According to geographical origin, non-native species are more numerous (58.65%), mostly originating from America (26.92%). Taxa of ornamental character are mostly represented (54.14%).
