Heavy rain this month of May made the grass grow. The Grass Pea (Lathyrus sphaericus) is hiding itself between the long stalks. Even if its small flowers are of a fluorescent orange colour, you really have to look for it to find it. The plant is tiny, and its elangated stems and leaves make it merge in the surrounding vegetation.
You can find it in limestone meadows where the farmer did not use too much fertilizer, or even in abandoned fields.
