Miracle growers

I was out playing in our garden with the children and spotted these colourful flowers. I am not a gardener at all and it always amazes me that they just seem to grow themselves year after year. I always mean to take photos but don't usually get around to it until it's too late so I nipped straight back inside to get the camera:

Ok so there's the odd weed in there too but fortunately my lack of botanical knowledge frees me to appreciate the beauty in all plants!
