Dandelion (Taraxacum officinale) is a flowering plant in the Asteraceae family. It is native to Europe and Asia, but is now found on every continent except Antarctica. The name dandelion comes from the French dent de lion, meaning "lion's tooth". This is due to the shape of the leaves, which are toothed and resemble the teeth of a lion.

Dandelion is an herb that has many uses. It is most often used in salads. The leaves can be eaten raw or cooked. They are a good source of vitamins A, C and K. Dandelion is also used as a diuretic. This means that it helps increase urine excretion and can be useful in treating conditions such as edema and high blood pressure. Dandelion can also be used to treat liver problems.

Dandelion is a hardy plant and can be found in a variety of climates. It grows best in well-drained soil rich in organic matter. Dandelion can be found in meadows, fields and wastelands. It is also a common weed in lawns.

Dandelion is a perennial plant, meaning it lives more than two years. The plant blooms from early spring to late summer. The flowers are yellow and are about 2.5 cm across. The flowers are followed by seed heads, often called "balls" or "clocks."

Dandelion is a very easy plant to grow. Seeds can be sown directly in the garden in early spring. The plant can also be propagated by division. This is best done in the fall.
