Swollen vein:

True thistles are in the family Cirsium, which comes from the Greek word ‘kirsos’ meaning swollen vein. They were also an herbal remedy used to treat swollen veins.

Encyclopædia Britannica:

If you ever had a set of these on your shelf, you may have noticed a thistle on the spine, the logo of these encyclopedias.

Of course, the thistle is also the flower of Scotland. The legend goes that a group of Scottish warriors were alerted to an invading group of barefoot, sneaking Norse invaders when one stepped on a thistle and shouted out in pain. Nemo me impune lacessit.

Monocarpic:

Some thistle species are monocarpic, meaning they die after flowering. This is different from annual because many don’t flower until their second year and are biennial. Some species take up to 8 years to flower!
