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.
