Thumbai (Leucas aspera) can grow in places where other plants would struggle, such as soils heavily contaminated with zinc and copper from pollution. It can often creep into agricultural fields and make itself at home among more desirable plants like sunflowers. When the leaves are burned, the smoke is a very effective insecticide.
