You cant duplicate the same plant in a review (not at present at any rate)
I could do something about that, but it would take a bit of a revamp, and I will have to put that off for a while.
The alternative is to add another plant of the same name
IG Pro doesnt let you add duplicates. However, if you add the same plant with some little variation, then it will.
Colour is one of the fields it checks, so if you add the same plant name and give it a slightly different spelling in the colour field it will accept it.
Is that OK as a workaround?
