I can't believe this is any sort of candytuft, as all my guide book tells me these are only found in the South East - but I can't find any sign of this in the same book. Seen in scrublnd near railway, West Yorks.
When posting id queries it would help to know what the leaves look like. And pic to show whole plant. It may be a wild flower....Alliaria petiolaris..but need to see the leaves to be sure. Common names include...jack-by-the-hedge. garlic mustard, garlic root, hedge garlic, sauce-alone, jack-in-the-bush, penny hedge and poor man's mustard. alliaria petiolata - Google Search
