The long mane of tentacles that stream out from the lion's mane jellyfish is stunning… literally! Look but don't touch when it comes to these jellyfish - they give a powerful sting.

As its name suggests, the Dwarf thistle is a low-growing plant that is almost stemless - its purple, thistle-like flower heads growing out of a rosette of spiny leaves.

Red dead-nettle does not sting. It displays dense clusters of pinky-red flowers in whorls around its stem, and can be found on disturbed ground, such as roadside verges.
