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 1.5-2.5 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. With the variety of forms and cultivars, there are also some hybrid crosses that can arise as well.
