The Scottish thistle is the national plant of Scotland which is why you see it on so many things from and about Scotland.

Legend had it that a long time ago when Scotland was still independent an English army attacked a Scottish castle, in the dark of night they stripped from their clothing to better swim the mote and jumped in only to find the mote dry and over'grown with thistles, their cries of pain woke the castle and saved the day for Scotland.

I don't know nothing about no pineapples.
