thanks again, Lorraine, I agree, these are very pretty flowers, the white seems to be a special kind of white, if that makes sense. The flowers in the upper half of the image will give you more of an idea of what I mean, as they are in the light.

thanks Carol. There are some blue flowers nearby, forget the name of them, but beside these white ones, they look really pretty. The hummers were supposed to like the blue flowers, but so far I haven't noticed them feeding from them :)
