Characteristics: This is probably one of the easiest Leguminosae to recognise. On the one hand due to its blue flowers, on the other hand because of the plants unmistakable smell (smell one leaflet between your fingers) of bitumen (shoe polish), hence its name. The size of the plant is fairly large: it grows to more or less one metre in height. It is very frequent along path- and road- sides and in fields. It flowers at the end of spring.
