Human Worlds

Some plants can survive anywhere, even the heart of the city. These "weeds", like the Ivy-Leaved Toadflax, can grow on walls and other shear surfaces without any soil. The plant grows and blooms towards the light to attract pollinators, but once the seedpods develop it will turn inwards seeking a dark crevice to grow in. Such cracks are all it needs to produce a new plant.
