Clovers are a type of weed with three leaves that appears in Animal Crossing: Wild World, Animal Crossing: City Folk, and Animal Crossing: New Leaf. Like typical weeds, players can pluck them from the ground or dig them out with a shovel in which case they disappear. Unlike typical weeds, they have no negative effects to the village if left alone. Clovers appear in patches of four, and will spawn from late February to early December.

Lucky clovers[edit]

Icon for the lucky clovers in New Leaf.

In Wild World, City Folk, and New Leaf, players have the possibility of finding a lucky clovers (known as the four-leaf clover in Wild World), but this is rare; there is only about a 1 in 40 chance for each clover to be a four-leaf clover. This item will be stored in the inventory. Placing a clover outside in town does not have any special effect on the perfect town rating as it only acts as a regular piece of flora. When it is dropped in one's house as furniture, it will be an open book with the clover being used as a bookmark. This will increase luck. It can also be worn in the player's hair. Four-leaf clovers are traditionally associated with good luck, a superstition that is also voiced by the player. If players place a clover in their house, it acts as a lucky item and gives them 7,777 points toward their HRA or HHA score.
