Our United States are home to the highest concentration of an extremely rare plant: a vampire albino redwood.

These vampires remain attached to the roots of their healthy, normal, parent trees (coastal redwoods can reproduce asexually by sprouting new shoots from roots or stumps), and survive by sucking energy from them. They can keep this up for a century.

According to Discover, only about 25 of these trees are known to exist, and eight of them are in a state park in California. Since they lack any chlorophyll, they can’t synthesize light to create energy, so they suck life out of normal, healthy plants.
