Unidentified heat-generating plant

This unnamed heat-generating species was brought to Earth by an alien scientist, and used by a group of criminals during a heist.

Biology
The plants somewhat resembles a small light orange tree, with small jagged appendages protruding from several places over its trunk, appearing to be leaves. Most notably, this plant emits extreme heat, enough to melt through steel, but only in a certain area. Any sensory inputs or other stimuli that prompt the plants to do so are unknown. In Earth's soil, which they can survive in, they can grow at incredible speed.
