Tesla trees

Tesla Trees are a fictional plant lifeform in Dan Simmons' Hyperion Cantos series. They are native to the planet Hyperion. They appear to store up electricity inside their body during certain seasons, releasing all of it in huge arcs of lightning from their crown, burning away all that was growing near them (or walking near them) and thus creating fertilizer. Together with other fictional plants such as Prometheus, Phoenix, and Fire Whip, they form a fictional ecosystem called Flame Forest.
