Yellow flowers

Lots of Fringe shows seem to have started already around the University at George Square. There are not many quiet corners left and it will only get busier as more people arrive to watch the shows.

Here's a blip of some lovely yellow flowers I noticed outside the Business School. I don't know what they're called and would welcome suggestions.

Our first Spanish class this evening was "muy bien"! It's a post beginners class, though and I feel my Spanish is very rusty. Hopefully, it'll improve to the point where I can ask for a beer, by the end of the four week course ;o)
