Carrizo, often referring to *Phragmites australis*, is a tall, perennial reed grass commonly found in the southwestern United States and Mexico. It's known for its aggressive growth and ability to form dense thickets, particularly along waterways. Think of it as the 'desert invader,' thriving in areas where water is scarce 🌵. While providing some erosion control, it often displaces native plants. It's like the plant equivalent of a land grab.
