Indeed it is pretty. But then even some weeds are pretty. Scotch thistle is gorgeous, but not a good thing to have in one's pastures.
We live in the country and we have a friend who was born in Scotland. She was having a birthday party and I sent my husband off to a neglected corner wearing the welding gloves to collect some flowers from a particulalry good looking Scotch thistle. We arrived at our friend's birthday party and presented her with the thistles shoved into an old jar and everyone fell about laughing at our joke. She put the jar and thistles on the mantle piece and we all got on with the party.
There were some late arrivals who had had to travel for many hours from Sydney to get to the party. They thought the 'flowers' were lovely and asked where they could buy some because they'd love to take a bunch home with them. All we country folk just about had a stroke on the spot.
