D. reflexa var. angustifolia (syn. D. marginata) differs in having a magenta tint to its flowers, a shrubby habit, and olive green leaves.

Dracaena reflexa was first described by Jean Baptiste Lamarck in 1786. It has been placed in several other related genera, including Cordyline and Pleomele. Dracaena reflexa var. angustifolia Baker – western Indian Ocean islands
Dracaena reflexa var. bakeri (Scott Elliot) H. Perrier – south east Madagascar
Dracaena reflexa var. brevituba H. Perrier – central Madagascar
Dracaena reflexa var. condensata H. Perrier – south east Madagascar
Dracaena reflexa var. lanceolata H. Perrier – Madagascar
Dracaena reflexa var. linearifolia Ayres ex Baker – Mascarenes, Madagascar
Dracaena reflexa var. nervosa H. Perrier – Madagascar
Dracaena reflexa var. occidentalis H. Perrier – west and south west Madagascar
Dracaena reflexa var. parvifolia Thouars ex H. Perrier – east Madagascar
Dracaena reflexa var. reflexa – north east Mozambique, western Indian Ocean islands
Dracaena reflexa var. salicifolia (Regel) Baker – Madagascar
Dracaena reflexa var. subcapitata H. Perrier – east Madagascar
Dracaena reflexa var. subelliptica H. Perrier – east Madagascar

Dracaena reflexa is a popular ornamental plant, both in the landscape and the home. It can be enjoyed as a specimen plant, accent, or pruned to create a border. Several cultivars have been selected, particularly variegated clones with cream and yellow green margins. It performs well as a houseplant, tolerating infrequent waterings. It prefers bright, filtered light, without direct sun exposure, restricted outdoors to zones 10–11. It has average water needs and should be fertilized bi weekly when actively growing. Although it can survive in relatively low light levels, the plant may grow spindly if given insufficient light. When grown indoors, temperatures of 18 °C to 25 °C (64 °F to 77 °F) should be maintained. It can be propagated via herbaceous stem cuttings. The cultivar Dracaena reflexa 'Variegata' has gained the Royal Horticultural Society's Award of Garden Merit. (confirmed 2017)

Traditional medicine practitioners of Madagascar have long believed Dracaena reflexa to cure malarial symptoms, poisoning, dysentery, diarrhea, dysmenorrhea, and to be useful as an antipyretic and hemostatic agent. The leaves and bark are mixed with parts of a number of other native plants and mixed into herbal teas. Its effectiveness in any such treatment remains unproven. The fruit of D. reflexa is also important to the diet of the Malagasy black and white ruffed lemur (Varecia variegata variegata). The Frégate beetle (Polposipus herculeanus), an endangered species endemic to Frégate Island (Seychelles), is also known to associate with this plant.

Dracaena reflexa var. angustifolia is also known as D. marginata, a name found in horticulture. This is a durable popular tropical house plant from Madagascar. The thin leaves are linear and a deep, glossy green color with red edges; typically 30–90 cm long and 2–7 cm broad, tapering to an acuminate point. It is a popular houseplant that needs little attention, with several cultivars available with the leaves variegated with red or pale yellow. It requires a minimum temperature of 15 °C (59 °F), and is more tolerant than most plants of dry soil and irregular watering, though liable to root decay in permanently wet soil. Because it requires minimal care it is very popular in offices where the constant heat and light suits its growing requirements. They can grow between 2.5–4 meters in height and will ultimately spread between 1.5 and 2.5 meters. There are many commonly used names to describe this variety that arise due to the various growth patterns and different cultivars. Some of the most popular are red edge dracaena, Madagascar dragon tree dracaena, dragon blood tree, and tree dracaena.

The plant can be grown in virtually any pattern, with the most popular being bush, straight cane, staggered cane, tree form, and custom character forms. The variety also has a handful of different cultivars from selective breeding. These include 'Tarzan', 'Magenta', 'Tricolor', and 'Colorama'.

It is one of the plants used in the NASA Clean Air Study and has shown to help remove formaldehyde. It is an effective air cleaner and is said to be among the best plants for removing xylene and trichloroethylene.
