Balsam ran away from the flower bed

This is the Balsam flower, which itself was sown at the foundation of the house. All other Balsams grow in a flower bed. How this flower got here is not known. He has very little land. It grows on one inch of free land between the paved path and the wall of the house. But this Balsam gets a lot of water. The roof of the house is directly above the flower. All rainwater from the roof flows into the roots of this flower.
