"Weeds" (also known as "The Lonesome Death of Jordy Verrill") is a darkly humorous short story by Stephen King.
[1] On Independence Day, a backwoods hick farmer in New Hampshire named Jordy Verrill thinks his newfound discovery of a meteorite will provide enough riches to pay off the remaining $200 (equivalent to $1,071 in 2023) of his bank loan, but instead finds himself overcome by a rapidly spreading plant-like organism that arrives in the meteorite when he ends up coming in contact with it.
The next day, Jordy now resembles a plant creature with a roundish head with no visible neck and round shoulders.
He is then visited by the ghost of his father (also portrayed by Bingo O'Malley), who appears in his mirror and warns him not to get in the tub as it is the water that the plants want.
A radio forecaster predicts long periods of rain and sunshine as the camera pans across Jordy's farm, now overrun with monstrous vegetation as some of it is starting to go down the road.
