The Catalpa Delavayi is an extremely common, tiny plant and can be found mostly in swamps. It blooms in late spring. It has thin, squared leaves, which are usually bright green. It also grows quite large flowers, which can be light red, dark silver, grey and dark yellow. These plants grow in tiny groups, but it's hard to control and maintain their growth. They can be eaten to relief a sore throat. As a defense mechanism the Catalpa Delavayi grows tiny thorns. They rely on water currents to carry their seeds away to reproduce. Once pollinated, they grow fairly large, inedible fruits.
