I found my first flowers yesterday near a cement wall of the entrance to the bridge that I walked over. I have no idea what they are -- maybe Katney will identfy them for me. They are very tiny and this is a macro shot but hard to tell since there is nothing but a wall in the background on which they seemed to be climbing..
Your EG Tour Guide identified them as VERONICA and I verified his answer on Google. (Both images and info) It said this about this flower:
Flowering - March - August.( It is almost March. . . )
Habitat - Open rocky woods, glades, waste ground, cultivated areas, fields, pastures, lawns, roadsides, (It was on the bicycle/walkers entrance to the I-205bridge) railroads.
Origin - Native to Europe.
Other info. - This little introduced species can be found throughout Missouri. This is one of the earliest little plants to bloom in the spring. (It isn't quite spring here yet. . . ) The earliest flowers tend to be smaller than the flowers that come later in the season. This is an easy species to ID in the field because of the small blue flowers, sessile leaves, and pubescent stems.The info in between {and) are my comments.
