I seem to have accidentally found a very small plant, with extremely tiny white flowers... Seems to be growing in a crack of the pavement. I've now put a few bricks around it, so that it doesn't get trampled accidentally. I think I've found the perfect plant for a small terrarium! But how to dig it out from the pavement? And what kind of special care will it require? Also, what is this plant??? This picture below (with the keys) is to give everyone an idea about how small this plant really is. And these below are an extreme close up of the tiny flowers... If the plant is so small, and flowers this tiny - Then will the seeds be microscopic???
