Dandelion Clocks Against A Summery Grey Sky

Did a search to find the correct name for dandelion clocks or helicoptors (my preferred name!!?) and found that they are of the species of Taraxacum and are tap-rooted biennial or perennial herbaceous plants, native to temperate areas of the eurasia and north and south america.
The leaves are 5-25 cm long, simple and basal forming a rosette above the central taproot.
The flower heads are yellow to orange coloured, and are open in the daytime but closed at night and the heads are borne singly on a hollow stem that rises 1-10 cm or more above the leaves and exudes a milky latex when broken.
A rosette may produce several flowering stems at a time and the flower heads are 2-5 cm in diameter and consist entirely of ray florets that mature into spherical seed heads called "blowballs" or "clocks" containing many single-seeded fruits called achenes.
Each achene is attached to a pappus of fine hairs, which enable wind-aided dispersal over long distances.
That is a long way to say that you pick and blow it (making a wish) and the dandelion clocks fly away to spread the weed all around the garden!!?
