Dittrichia viscosa, also known as false yellowhead,[2] woody fleabane,[3] sticky fleabane and yellow fleabane, is a flowering plant in the daisy family.
Dittrichia viscosa is a highly branching perennial common throughout the Mediterranean Basin. It has long, narrow leaves that are pointed at both ends and have teeth along the edges and glandular hairs on the surfaces. One plant can produce many yellow flower heads each with as many as 16 ray florets and 44 disc florets.[4]
Originally, the species was found mainly in dry riverbeds and abandoned fields up to a 1500 m (5000 feet) elevation. Nowadays it is quite common in roadsides and ruderal habitats, even in urban areas. It is considered an invasive species in Australia.[5] 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.
Despite the fresh-looking green color of its leaves and its attractive inflorescence,[6] this plant is sticky and has a certain smell that most people find unpleasant. It contains an essential oil[7] and has been used in traditional medicine since ancient times, especially in the Levant, as an astringent.[8]
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.
