Cactus

Much to my surprise I found this was flowering - the first time it has done so, Tiny flowers - about 5mm across.

Today's Shoot Like a Pro e-conference was superb. I found Chris Packham's talk particularly interesting - I'd always thought of him as a champion of the natural world and an excellent presenter, but I hadn't realised that he is a superb photographer as well, and the amount of time and planning that goes into his work is fantastic.
