A late-flowering plant, Autumn gentian displays pretty, mauve, tube-like flowers atop its reddish stems. It favours dry, chalk grassland and sand dune habitats.

This bumpy shell lives up to its name and lives partly buried in the seabed along the west coast of Great Britain.

Look for Water avens in damp habitats, such as riversides, wet woodlands and wet meadows. It has nodding, purple-and-orange flowers that hang on delicate, purple stems.
