COLUMBINE : Aquilegia vulgaris.
This is a pleasant plant found widely in West Dunbartonshire. It derives from Europe, but you will see are most likely escaped domestic varieties, purple, pink or white.
Wikipedia tells us that it was considered sacred to Venus; carrying a posy of it was said to arouse the affections of a loved one. Nicholas Culpeper recommended the seeds taken in wine to speed the process of childbirth. In modern herbal medicine it is used as an astringent and diuretic. [Wiki].
In spite of its use in medicine it is a member of the poisonous Ranunculus family and all parts of the plant, including the seeds, are poisonous if ingested. It is possible that inhaling the crushed seeds dust or otherwise absorbing oils from them may cause poisoning or at minimum exhibit symptoms of poisoning.
