Fam: Asteraceae (Compositae)
Genus: Inula L.
English Name: YellowheadDescription: Half bushes or perennial rhizome plants, rarely biennial herbaceous plants. Stems single or several, erect or ascending, usually branched at the top, rarely simple, fibrous to woolly fibrous or almost glabrous. Leaves consecutive, entire, serrated or finely serrated, rarely entire, on petioles or sat down. Baskets heterogamous, with many blossoms, hemispherical to hemispherical disc-shaped, single or few to numerous, singly on petioles gathered in apical thyroid or paniculate complex inflorescences. Integumentary leaflets in several (up to 6 - 7) rows, unequal, rarely almost identical, tile-like overlapping, grassy, leathery or membranous, when ripening the fruits spread or folded back. Flower bed flat or slightly convex, bare without bracts. Blossoms uniformly colored, peripheral tongue (sometimes the tongue very short and difficult to notice), feminine, few to numerous, in 1 (2) order; inner tubular, bisexual, numerous, with a corolla on top 5-parted. The style with dull fibrous stigmas. Anthers linear, basically arrow-shaped, with 2 ciliated appendages. Fruits uniform, prismatic cylindrical, finely longitudinally ribbed, glabrous or shortly fibrous. The kite in a row, finely dusted, at the base free hairs. Insect pollinated; propagated by seeds and rhizome shoots.

Inula is a large genus of about 90 species of flowering plants in the family Asteraceae, native to Europe, Asia and Africa.
They may be annuals, herbaceous perennials or subshrubs that vary greatly in size, from small species a few centimeters tall to enormous perennials over 3 m (10 ft) tall. They carry yellow daisy-like composite flowerheads often with narrow ray-florets.
Some common characteristics include pappus with bristles, flat capitulum, and lack of chaff.
Several species are popular flowers for the garden, with cultivation going back to antiquity. The smaller species are used in rock gardens and the more common larger ones, which tend to have very coarse foliage, in borders.
