Weed

Weeds in the series resemble small clumps of grass that change colour according to the seasons. Three new weeds appear in the player's town each day. They do not necessarily have to be pulled up, but will effect the towns environment and forgetting to pull out the weeds will result in the appearance of a rafflesia, a large, red flower which attracts flies and further lowering the enviroment rating. Weeds are also contaminants as they will lower the chance of flowers breeding.

Another form of weed is the clover, which appears as four clover plants which appear two by two in one grid. However, clovers may result in a four-leaf clover when pulled out from the ground. A four-leaf clover is an item which can be worn in the player's hair or placed in the player's house as a clover stuck to the page of a book. There is speculation as to whether or not it effects luck, but the lack of evidence suggests that it doesn't.
