Dittrichia viscosa, also known as False Yellowhead, Sticky Fleabane, Woody Fleabane and Yellow Fleabane, is a flowering plant in the daisy family.

This perennial plant is common throughout the Mediterranean Basin. Originally it was found mainly in dry riverbeds and abandoned fields up to a height of 1.500 m. Nowadays it is quite common in roadsides and ruderal habitats, even in urban areas. It is considered an invasive species in Australia.^[1] The False Yellowhead is a tough plant, very resistant to adverse conditions and degraded environments. It is important as food for the caterpillars of certain butterflies and moths, like Ioana iolas.^[2]

Despite the fresh-looking green color of its leaves and its attractive inflorescence,^[3] this plant is sticky and has a certain smell that most people find unpleasant. It contains an essential oil^[4] and has been used in traditional medicine since ancient times, especially in the Levant, as an astringent.^[5]

It is an important plant in Catalan tradition, often mentioned in adages and proverbs. One adage says that: "els raïms són madurs quan floreixen les olivardes.", the grapes are ripe when the Yellow Fleabane blooms.
