As children we thought it was one of the wonders of the world!
I'm glad they still do it each year, in spite of the number of plants and the number of man hours involved. (Still cheaper than the trams of course.....sorry Edinburgh folks, just joking. A cheap dig, I admit!)
I should perhaps explain that there is in Scotland a friendly rivalry between east and west and between Edinburgh and Glasgow, and being a Glasgow girl, I sometimes join in the badinage/schadenfreude....
Edinburgh was the first city to have a floral clock (though Glasgow had trams - I wonder why we got rid of them?) and the reason I am indoors writing about it mid-afternoon is that we in the west have midgies which make gardening all but impossible on moist still days - the east suffers less in this regard.
