Traveller’s Joy

"Some know this plant as old man’s beard but for me it will always be traveller’s joy, the name given by the 17th-century herbalist John Gerard, who delighted in the way it “maketh in winter a goodly shew, covering the hedges white all over with his feather-like tops”.
(Phil Gates, The Guardian)
The white hairs are transformed styles, with all the reddish-brown seeds in the centre. There are fewer feathery hairs on Traveller's Joy than on Virgin's-Bower. When dry the feathery plumes spread out at an angle of 120° ready for the wind to carry them away with their attached seed.
