16 weird plants that seem more supernatural than natural

8. Hemlock (Conium maculatum)
The extremely hardy, poisonous hemlock is an invasive plant that can grow to heights of 2.4 metres. Its seeds and roots are especially poisonous. If being deadly was not enough to put you off, hemlock also has a repulsive smell which can be carried on the wind. In ancient Greece, hemlock was used to poison prisoners, including the philosopher Socrates.
