The Catalpa Quadrifolia is a common, tiny plant and can be found in dark and wet places. It blooms once a year, for 3 weeks. It has thin, lobed leaves, which are usually blue-green. It also grows small flowers, which can be dark red, light bronzeblack. These plants grow in huge groups, but it's fairly simple to control and maintain their growth. They can be brewed as tea. As a defense mechanism the Catalpa Quadrifolia has a thick, wooden stem. They rely on water currents to carry their seeds away to reproduce. Once pollinated, they grow small, inedible nuts.
