The Common Dandelion (Taraxacum officinale) gets a bad rap. ‘In the country’ we can ignore the stigma associated with having dandelions in our fields and enjoy the bright yellow color they share on a cloudy or rainy day. They will bloom year round if the winter is mild. In a cold winter, as we have just had, they take a while to get started. In cool weather in late winter-early spring, they will bloom on short stalks. As the weather warms, they bloom on longer stalks and each plant may bear multiple blooms simultaneously.
A number of flowers – members of the family Asteraceae - resemble the Common Dandelion; these include Krigia species, Sonchus asper, and Pyrrhopappus carolinianus. Flower color and leaf shape are useful to differentiate one from another.

Even the empty seed head is quite striking if you can ignore that fact that this is a weed.
The Common Dandelion is native to Eurasia but is found worldwide. It occurs in all states and provinces in the United States and Canada, respectively.
