Crassula – the potent invasive plant being challenged by a microscopic mite
Crassula helmsii (also known as Australian swamp stonecrop, New Zealand pygmyweed, or crassula) is an aquatic or semi-terrestrial succulent plant. The species was initially introduced to the UK in the early 1900s as an oxygenating pond plant. It originates in Australia and New Zealand, as its common names suggest.
