Christmas cactus is a popular holiday plant that is known for its festive appearance and delicate flowers. Like most plants, Christmas cactus needs sunlight to grow and thrive. However, it is important to note that too much direct sunlight can actually harm the plant, as it can cause its leaves to burn. Instead, it is recommended to provide the plant with bright, indirect sunlight, such as that which comes through a window or is filtered by a sheer curtain.
