A large genus of flowering plants in the family Asteraceae. They are native to Europe and Asia, and two species, T. officinale and T. erythrospermum, are found as weeds worldwide.
The common name Dandelion is given to members of the genus, and like other members of the Asteraceae family, they have very small flowers collected together into a composite flower head. Each single flower in a head is called a floret.
