Thistle (Fallout 4)

Thistle is a consumable item

Gameplay
Thistles can be found growing on irradiated thistle plants in the Commonwealth. When approached, the thistle will explode causing a cloud of highly radioactive dust to fill the air. The radiation is more powerful based on proximity to the plant itself, up to 22 rads per second. The explosion occurs about five seconds after being triggered, giving plenty of time to simply collect the thistle and stop the detonation, or walk out of its range.

Locations
Thistles tend to be found away from settled or urban areas.
 * Eight can be found just north of USAF Satellite Station Olivia and east of the robotics disposal ground.
 * Three just in front of the Red Rocket truck stop.
 * Another four can be found to the west, on the hill north of the water tower.
 * Two outside of Finch farm, in front of the house by two trees and some metal barrels.
 * Two northwest of the red crane near Vault 111.
