Under European Union regulations, “it is an offence in the UK to keep, cultivate, breed, transport, sell or exchange this species, or release it, intentionally or unintentionally, into the environment.”
Until we can find a native species that will perform in the same way in classroom photosynthesis experiments, we are using Egeria najas. See Egeria info.
