Poinsettias are popular flowering plants known for their vibrant red and green foliage, often associated with the Christmas season. Native to Mexico, these plants can grow up to 10-12 feet tall in their natural habitat but are typically sold as potted houseplants. The colorful parts are actually modified leaves called bracts, while the true flowers are small and yellow. Poinsettias thrive in warm environments and prefer indirect sunlight. They require well-drained soil and should be watered when the top inch of soil feels dry. With proper care, these plants can last for several months, adding festive cheer to homes during the winter months.
