Th "mini" weeds of spring (up close)

It isn't March yet, but some of my favorite weeds are already starting to blossom.  I love looking at the very mall flowers of the early ground flowers (weeds?).  This guy (bittercress) seems to grow everywhere and is very prolific.  You can see the flowers and the maturing seed pods on the central stem.  Although they start out very small, they can grow to be 4 - 6 inches wide for the whole plant.

The clay dish is 3 inches in diameter.  The flower stem is shown below in side-by-side stereo

and as an anaglyph.
