Can Madagascar periwinkle grow indoors?

Yes, Madagascar periwinkle can successfully grow indoors with proper care. This plant requires full sun to partial shade light conditions, which means you should place it near a window that receives appropriate light exposure. East or west-facing windows are often ideal. Maintain indoor temperatures between 65-75°F (18-24°C) for optimal growth. Indoor humidity can be a challenge - Madagascar periwinkle prefers moderate to high humidity. You can increase humidity by grouping plants together, using a pebble tray with water, or running a humidifier. Ensure good air circulation to prevent fungal issues, but avoid placing the plant near heating or cooling vents. Regular rotation of the plant ensures even growth on all sides.
