The Bumelia Arboreus is a very common, medium-sized plant and can be found only at the bottom of deep cave systems. It blooms once a year, for 2 weeks. It has wide, oval leaves, which are usually dark orange. It also grows quite small flowers, which can be silver, light blue, light brown, dark pink and dark purple. These plants grow alone, often without another in sight, but it's hard, especially without experience, to control and maintain their growth. They can be eaten to relief a sore throat. As a defense mechanism the Bumelia Arboreus grows large thorns. They rely on winds to carry their seeds away to reproduce. Once pollinated, they grow small, inedible fruits.
