The Buddleia Delavayi is an extremely common, tall plant and can be found in most subarctic regions. It blooms once a year, for 4 months. It has large, paired leaves, which are usually olive-green. It also grows decent sized flowers, which can be blue, red and light blue. These plants grow in large groups, but it's extremely difficult to control and maintain their growth. They can be cooked and eaten. As a defense mechanism the Buddleia Delavayi mimics the overall look of a different, poisonous plant. They rely on cloning themselves by growing a new specimen to reproduce.
