This expression, From the Grassroots, I understand to mean something started from the bottom, something seen from the lowest. A very close look.
We don't usually consider grass, we take it as a whole. From a stadium lawn to the grass in the yard, the grass is like a green carpet. But what if we went closer? We'd definitely notice a different world. A small world, like Gulliver's. An interesting and beautiful world!
I have a little yard with lots of flowers and a patch of grass. Beyond the visual pleasure, beyond the help I get for relaxing and clearing stress, my little yard is perhaps the main reservoir of subjects to photograph. I have managed, over decades, to collect many flowers and a few trees. I try to use their image in my photographs.
Still with an eye for the "pedigree" flowers, if I may say so about the selected and famous flowers, I have forgotten the little patch of grass. I have a habit. When I go to the country or to a field or a forest I pick small plants with roots and try to plant them in the yard. Some, more hardy, adapt to the new place and accept to live the rest of their life in my yard. It gives me great pleasure to see them bloom each spring, but human gratitude is short and bitter. Attracted to the big and important flowers, I often ignore the small and hidden beauty in the grass.
Thankfully, I have now remembered and watched from the grassroots. The little daisies, tucked away on the edge to avoid the lawnmower, lift their heads to the sun. Many years ago I brought a few plants from far away, from my grandmother's house. Now they have multiplied, trying to poke their heads out of the grass and seem to be enjoying themselves with me, even though I have forgotten about them. Watching from the grassroots reminded me of my childhood!
