In most such species, the tumbleweed is in effect the entire plant apart from the root system, but in other plants, a hollow fruit or inflorescence might detach instead. [1] Xerophyte tumbleweed species occur most commonly in steppe and arid ecosystems , where frequent wind and the open environment permit rolling without prohibitive obstruction.
Scientists at the University of Eastern Piedmont wrote that they had identified hemlock water dropwort (Oenanthe crocata) as the plant responsible for producing the sardonic grin. [ 14 ] [ 15 ] This plant is a possible candidate for the "sardonic herb", which was a neurotoxic plant referred to in ancient histories.

This plant is native to the tropical dry forest of Central America, South America (Mexico to Brazil and northern Argentina) and the Caribbean. In these natural areas it occurs from sea level to over 600 metres (2,000 ft) above sea level and where the rainfall is 750 to 2,400 mm (30 to 94 in) per year.
The roots lose the ability to absorb water and nutrients. [7] Lightning strikes kill or injure plants, from root crops like beet and potato, which are instantly cooked in the ground, to trees such as coconut, through effects such as sudden heat and pressure shock waves created when water inside the plant flashes to steam. This can rupture stems ...
