What does thistledown mean?
Thistledown is the soft, feathery material attached to the seeds of a thistle. When a thistle releases its seeds, each seed carries a delicate tuft that catches the wind, allowing the seeds to travel far from the parent plant. The word can refer to an individual floating seed tuft or collectively to the light mass of seeds visible in the air. It is especially associated with summer meadows, quiet landscapes, and poetic descriptions of movement, delicacy, and impermanence. In figurative use, thistledown often describes something light, fragile, or liable to be carried away by circumstances. Although the term occurs in both British and American English, its literary associations make it feel particularly evocative rather than strictly technical. In botany, the specialized term for the tuft or other appendage aiding seed dispersal is pappus.
nounThe soft, downy tuft attached to a thistle seed, or the collective floating seeds of a thistle. The light seed tufts are often carried through the air by the wind.

Where does thistledown come from?
Thistledown is an English compound formed from thistle and down. The first element continues Old English þistle, with related Germanic forms such as German Distel and Dutch distel; the second comes from Old English dūn, originally meaning soft feathers or fluff and later extending to fine downy material. The compound developed by applying the sense of down to the seed tufts of a thistle.
