Abstract The results of present study on homegarden floristic structure, composition, use and household economy in the 6 rural villages (Ariyaperumalvilai, Azhagiapandiapuram, Elankadai, Maravankudiyiruppu, Thandanayagankonam) of Kanyakumari District, Tamil Nadu, reveals that 95 plant species belongs to 82 genera and 46 families were identified from 215 homegardens located in the study areas of six villages; Homegardens selected for the study were classified into four types as hutted home, tiled home, terraced home and storied home; Total area of household surveyed from all six villages was 50,020.02m2; the total area of homegardens studied in six villages was 17953.80m2; Among the home gardens surveyed, 62.33% in overall study area were fenced with a maximum of 97.50% fenced home gardens found in Ariyaperumalvilai area as compared to others; Out of 95 plant species recorded 78 were cultivated, 14 were wild and 3were both cultivated as well as wild. Of these, 33 shrubs, 31 trees, 18 herbs and 13 climbers; Most of the home gardens plants are possess multilayered plants and that are mostly ornamental and multipurpose plants; Smaller gardens possessed by people of lower economic level are dominated by annual crops while larger home gardens possessed by people of higher economic level are dominated by perennial trees for commercial purpose and plants for beautification; Maximum 35 plants were used as whole plant by the households as compared to other plant parts used; Based on use category, the plants from overall homegardens have been classified into 26-ornamental, 21-vegetable and multipurpose plants of each, 18-edible, 7-medicinal, 1-fuel and furniture use plant of each and 15-plant species were commonly found in all the 6 village homegardens. The diversity indices estimated for overall homegarden plants as H’=1.561, (Shannon-Winner diversity), Species Richness (R=25.868), Species Evenness (E=0.789), Simpson’s Diversity Index (λ=0.059) and Diversity Index (DI =0.022). Among the study area, maximum SWI (H’=1.543) and Species Richness (R=22.703) was noted in Ariyaperumalvilai while the Species Evenness (E=0.879) in Thandanayagankonam, the Simpson’s Diversity Index (λ=0.119) and the Diversity Index (DI=0.093) was also noted. Keywords: Homegarden, Plant diversity, Rural homegarden, Village homegarden, Kanyakumari District.
