"The Justice League members are attacked by marauding giant plants when an alien \"Johnny Appleseed\" and his son come to Earth in a misguided attempt to restore its ecological balance. The heroes are unable either to stop the dam-age being done by the extraterrestrial plants, or to convince the visitors that they are doing more harm than good, until they pretend to assist in the planting campaign. The aliens are then deprived of their power-staffs, without which even they cannot survive in the environment being created by their plants. Realizing their error, they depart for their own world."@en . . . . . "Featured Characters\n* \nSupporting Characters\n*"@en .
