These are the same as the yellow dandelions, except these are a bit smaller, and more colorful.
Actually, some people grow dandelions because every part of them are edible and the leaves are good in a salad! You can find dandelion variants online that grow bigger, greener leaves just for that reason, to eat them after! I dont know if the pink ones are edible, but all I can say is they are rather pretty. :)
