Ecballium is a genus of flowering plants in the family Cucurbitaceae containing a single species, Ecballium elaterium, also called the squirting cucumber or exploding cucumber (but not to be confused with Cyclanthera explodens). It gets its unusual name from the fact that, when ripe, it squirts a stream of mucilaginous liquid containing its seeds, which can be seen with the naked eye. It is thus considered to have rapid plant movement. It is native to Europe, northern Africa, and temperate areas of Asia. It is grown as an ornamental plant elsewhere, and in some places it has naturalized.
