Common Name: dandelion, common
Species: Taraxacum officinale Weber in Wiggers
Bayer Code: TAROF

Dandelion is a perennial weed with a thick, fleshy taproot and no stem. Leaves grow in a rosette from the crown. They are long, narrow, irregularly lobed, and lance shaped. The lobed tips are often opposite each other and pointing toward the crown. Leaves are often purple at the base and leaves and flower stalks emit a milky white sap when broken. The deep golden yellow flowers are borne in heads on long hollow stalks. Blossoms soon mature into spherical clusters of whitish fruits, like white puffballs, composed of parachute-like seeds. Seeds are carried by the wind. Cat's ear dandelion is similar to common dandelion. Common dandelion plants can be distinguished because young leaves do not have hairs, whereas cat's ear dandelion leaves have dense hairs.
