The poinsettia is a popular flowering plant known for its vibrant red and green foliage, often associated with the Christmas season. Native to Mexico, it thrives in warm climates and can grow up to 10-15 feet tall in its natural habitat. The colorful parts of the plant are actually modified leaves called bracts, while the true flowers are small and yellow. Poinsettias require bright, indirect light and should be watered when the soil feels dry. They are sensitive to cold temperatures, so it's important to protect them from drafts. With proper care, poinsettias can last for several months, making them a festive addition to holiday decorations.
