Tiny Flowers

Have no idea what flowers these are but it seems to be some kind of weed where these lovely blue flowers clusters at the end of the green grasslike plant. I had trouble with focus as these were really tiny flowers! and everytime I wanted to get a closer shot, the picture on my camera would just blur out. Well I did manage to capture a few good ones...of these teeny tiny flowers! Gosh such work it was with the focus.
