Dandelion

Dandelions are weeds that act as flowers in the game and appear randomly in the player's town after March. They look like the yellow cosmos and have a color similar to the yellow tulips’, just like their real-life counterpart. After a few days, they become a Dandelion Puff. If the dandelion puffs are left alone for a few days, it will disappear from the town. Dandelions are considered flowers in the game and do not affect the town's environment and will grow even when the "Keep Town Beautiful" ordinance is up in. If any dandelions are planted or are still around in winter, it will remain as a flower until March, then it will turn into a dandelion puffs.

Dandelions
The player can plant dandelions around town or use them as furniture items. The player can also sell them to Tom Nook. Dandelions can be used as handheld items.

In Animal Crossing: City Folk, the dandelions are much more realistic, complete with seeds. The player has the ability to wear the dandelion before it transforms into a dandelion puff.

Dandelion puffs
The player can hold a dandelion puff; while holding one, the player can press "A" to blow on the dandelion puff, resulting in the seeds floating away. This can be done only for fun, and has no important use.
