The Dracaena marginata, commonly known as the Madagascar Dragon Tree or Red-Edged Dracaena, is a popular and easy-to-care-for indoor plant. Here are some key features and care tips for Dracaena marginata:

1. Appearance: Dracaena marginata has long, slender, arching leaves that are green with red or burgundy edges. The plant can reach heights of several feet, and its distinctive foliage adds a touch of elegance to indoor spaces.

2. Light: Dracaena marginata thrives in bright, indirect light but can tolerate lower light conditions. It can also adapt to some direct sunlight, but prolonged exposure to intense sunlight may lead to leaf burn.

3. Watering: Allow the top inch or two of the soil to dry out before watering. Dracaena marginata prefers slightly drier conditions and is susceptible to root rot if overwatered. Ensure good drainage and avoid letting the plant sit in standing water.

4. Temperature: Maintain a temperature range between 65-80°F (18-27°C). Dracaenas are sensitive to cold drafts and should be protected from temperatures below 50°F (10°C).

5. Soil: Use a well-draining potting mix, such as a mix formulated for tropical plants or a general-purpose potting soil. Ensure the pot has drainage holes to prevent waterlogging.

6. Fertilization: Feed the plant with a balanced liquid fertilizer every 4-6 weeks during the growing season (spring and summer). Reduce or stop fertilizing in the fall and winter when the plant's growth slows.

7. Pruning: Prune the plant to maintain its shape and remove any yellow or dead leaves. Dracaena marginata can be pruned to encourage branching and denser foliage.

Dracaena marginata is valued for its striking appearance and low-maintenance care requirements, making it a popular choice for homes and offices. It's important to adjust care based on the specific conditions in your environment, and always consider the plant's individual needs.
