The objectives of this research were to study the species of fragrant plants in Suan Mai Hom, Rajamangala University of Technology Isan, Surin campus, and study the fragrant plants’ application for landscape architecture use. Results showed 60 different species, 51 genera, and 29 families which were classified into 24 species of tree (40%), 14 species of shrub (30%), 11 species of scandent (18.%), and
7 species of the climber (12%). The family with the most plant was Annonaceae and Apocynaceae
(9 species each). The most white-toned flowers (58%), most of them bloom year-round (57%) most with a light fragrance (57%), and the most common flowers bloom for 2-3 days (32%). All off these fragrant plants were useful in landscape architecture as follows: trees used as shade such as Calophyllum inophyllum, Fagraea fragrans, and Mimusops elengi, shrubs used as screen filters and reduce unpleasant smells such as Ixora finlaysoniana, Gardenia jasminoides and Nerium oleander, climber used as pergola and climber fence such as Antigonon leptopus, Bignonia magnifica and Combretum indicum.

Choosing the right fragrance level for near and far, duration of space use, blooming period of flowers, create an atmosphere of the garden that smells fresh, attraction and used for other benefits such as herbs, food, culture, and economy.
