Are plants a necessity or a luxury?
A new campaign says we should pay less tax on plants because they are good for the environment and mental health.
It's being backed by the National Garden Scheme at a time when house plants are becoming increasingly popular - particularly among young people who can't afford gardens.
In the UK, plants which don't produce food are subject to full VAT (Value Added Tax) at a rate of 20%. Whereas in other European countries, it can be at least half that.
