[Note Guidelines] Photographer's Note
Onopordum L. is a genus of about 40 species of thistles belonging to the family Asteraceae, native to Europe (mainly the Mediterranean region), northern Africa, the Canary Islands, the Caucasus, and southwest and central Asia. They grow on disturbed land, roadsides, arable land and pastures.

They are biennials (rarely short-lived perennials) with branched, spinose winged stems, growing 0.5-3 m tall. In the first season they form a basal rosette of gray-green felted leaves and rarely a few flower heads. In the second season they grow rapidly to their final height, flowering extensively, and then die off after seed maturation.

The leaves are dentate or shallowly lobed to compound with several pinnatifid or deeply cut leaflets, and strongly spiny.

The terminal flower head is typical for thistles, a semi-spherical to ovoid capitulum with purple (seldom white or pink) disc florets. There are no ray florets. The receptacle is glabrous with dentate margins. The tube of the corolla is slender, sac-shaped and symmetrical. The anthers have awl-shaped outgrowths on the top. The capitula have several overlapping rows of leathery basal simple linear-lanceolate spines. These are smooth to slightly pubescent.

These plants propagate only by seed. The seed heads mature in mid-summer, releasing their seeds. The fruit is a glabrous achene, 4-6 mm long and with 4-50 ribs. The pappus consists of many rows of simple, fine to minutely rough hairs, united in a circular base.

Onopordum species are used as food plants by the larvae of some Lepidoptera species including Coleophora onopordiella (feeds exclusively on O. acanthium).

Hallo Umar
How beautiful is this lavender flower. I also like the composition as a whole. The details captured are great and is clearly seen, I especially refer to the thorns on the stem and the unopened and semi opened flower buds. It is such a simple and basic image, yet it is so beautiful and have and certain magnetism to it. I can only but imagine looking at a whole field filled with these flowers. What a delightful view! The colours in this image are impressive. Oh and before I forget, I did see the little bee on the top, but sorry the flower is the star of the show and for that reason I have also placed it into my theme “My purple obsession” Kind regards and thanks for sharing.
