Clovers are a type of weed with three leaves that appear 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. 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.

Four-Leaf Clover[edit]

If plucked from the ground, most clovers will disappear. However, players have the possibility of finding a Four-Leaf Clover, which are called Lucky Clovers in Animal Crossing: New Leaf, 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.
