"I'm just sitting here watching flowers in the rain / Feel the power of the rain making the garden grow" to quote the lyrics of an oldie but goldie from the sixties. Roy Wood and The Move I think?
 There's not many flowers but there's been plenty of rain and the skies are about as grey and gloomy as they can get in the daytime. 
 Rather implausibly however this African Daisy in the front garden flowers every year round about now. At least I think it's known as African Daisy and is of the Osteospermum genus. Anyway it's a cheery contrast to rainy London streets.
