From the latest county cricket matters magazine Graham Coster writes
"Trees make cricket grounds, but cricket grounds are becoming stadiums. They're becoming stadiums because these days they're really there for just the big showdowns which apart from test matches, never see a red ball."
I have to confess my heart sinks whenever I attend New Road these days and there are black sightscreens in use and seats taken up by a temporary black comms box.
I do think there should be more greenery within the actual stadium we use. Edgbaston (fitting as it is for putting on great test matches and the Blast Finals Day and I'm led to believe the 100 aswell) never has been the most aesthetically pleasing ground when empty (looks stunning when full mind) but at least back in the day with the old pavilion you had the trees within Cannon Hill Park to enhance the view from the City End and the flower baskets added a nice touch
Also;
"Is draping a glorified bedsheet over a bank of seats really the best we can do for sightscreens?"
I think this is something that needs addressing at Edgbaston amongst several venues the ground needs to improve the way it is turned out the way for instance Trent Bridge is able to. I don't think Trent Bridge is necessarily a nicer ground (odd shaped outfield for one and some of their new stands are downright weird) but they do seem to make more of an effort on the aesthetic front IMHO
