The study was carried out from August 2019 to August 2020 at five major parks in Ho Chi Minh City. We aimed to survey the lighting system including bulb types, lamp types, illumination type, and average horizontal illuminance. The study was carried out by several methods such as a questionnaire of the characteristics of the lamp, observing, measuring, analyzing, synthesizing data, and evaluating. We divided each park by area, for example, main gate, side gate, main axis, branch road, lawn, activity area for investigation. The result showed that the parks having LED and HQ compact bulbs, which were popular chandeliers. Most parks had direct lighting to provide panoramic illumination, but did not reach the average horizontal illuminance. We propose an aesthetic illumination design for the central area of ​​the park with ideas from the history of the park's formation and development. The research results contribute to the improvement of the lighting system for the parks in Ho Chi Minh City.

The study was conducted from January 2021 to April 2022 in a number of public parks, residential parks in urban areas, major streets and boulevards, and coffee shops in Ho Chi Minh City. The study was performed by using survey forms, taking pictures and collecting samples. Identification of trees was done by morphological comparison and analysis of collected data, and then information was used for landscape design via using professional design softwares. The results showed that 23 species belonging to 20 genera of the Arecaceae family were identified. Public parks had 22/23 species while residential parks, coffee shops and streets had 17/23 species, 8/23 species and 4/23 species, respectively. Trees of the Arecaceae family identified included 16 species with solitary stem and pinnate (69.5%) and 7 species with clustered trunk and palmate (30.5%). Sketchup, Lumion, and Photoshop softwares could be used for conceptual design that combines the palm trees and other species in the landscape.

This research was carried out from October 2017 to October 2018 at some ornamental plant stores and nurseries in district 7, Go Vap district, district 10, Tan Binh district and Binh Chanh district. These are important ornamental plant trading and producing areas in Ho Chi Minh City. This study aimed to identify and analyse the potentials of using ornamental flowers, plants and trees for garden design. The investigation was conducted through questionnaire surveying, morphological comparison, species identification. The collected data was then statistically analysed. We divided these districts by zones and routes for the invesgation. There were 542 identified ornamental plant species in Ho Chi Minh City. According to the analysis of 7 important groups of ornamental plants such as tree trunks, shape of the tree, leaves, and flower groups, the bonsai pots for interior display, with large leaves, dark green to light green colors, large flowers, height from 0.1 to 1 m and no fragrance is common. Briefly, the obtained results would contribute to the design and construction of gardens in Ho Chi Minh City

The objective of the study was to identify some of common ornamental plants functioned as medicinal plants. The study was carried out in the Ho Chi Minh City, from September 2016 to June 2018 using some methods such as survey, identification, statistics, and applying these plants in garden design with site analysis, computer-aided design and drafting base on main idea. One hundred and twenty popular species belonging to 69 families with medicinal values were identified. Two cases for concept design, instant tree list, shrub and cover list were also proposed. The completed design drawings included function layout plan, master plan, sections and some details of garden, master perspective, detailed perspectives.

The study was conducted from June to September 2020 in Ho Chi Minh City. This research aimed to identify the palm species and incorporate them into the garden design. To investigate the species, 85 ornamental plant stores and nurseries were surveyed in Go Vap district, District 7 and at Highway 22. Then, morphological comparison method was used for plant species classification. According to the analyses, this region had 25 species belonging to 22 genera in the Arecaceae family. Twenty two of the 25 species surveyed were imported and 03 being native to the area. The majority (68%) was solitary-stemmed palms, with the remaining 08 species having clustered trunks (32%). To incorporate palm trees into the garden design, Sketch-up, Lumion, and Photoshop software were used.
