Dracaena marginata - Rainbow Tree

Dracaena marginata - Rainbow Tree

Dracaena marginata 'Tricolor', or Rainbow Tree, is a great cultivar of Dracaena marginata first found in Japan. The cultivar was developed in Puerto Rico and Florida, and was first sold in 1973. The multi-colored ribbon-like leaves are striped with a cream center between green with rosy-red margins. The gray stems have prominent leaf scars. Plant will reach approximately 15 feet (3 m) in height. Since its introduction in 1973, it has been one of the favored houseplants. They are of easy culture.

Blooming: I have worked with many cultivars of Dracaena marginata and have yet to see one bloom.

Culture: Dracaena marginata 'Tricolor' will take a wide variety of light condition, but they have the best leaf color in bright light. In the greenhouse, we use a soil mix consisting of 1 part peat moss to 2 parts loam to 2 parts sand or perlite. Even though the plants are very drought resistant, we water them on a regular basis and fertilize them monthly with a balanced fertilizer. During the winter months, the temperatures are dropped to 55°F (13°C) at night and water is restricted to only enough to keep the leave from dropping. Fertilizer is withheld during this period.

Propagation: Dracaena marginata 'Tricolor' is propagated from cuttings in spring.

Dracaena marginata 'Tricolor' was featured as Plant of the Week July 7-26, 2006.
