Quizmonster, it is a garden plants quiz question. I have already posted it on Q & P but am not having much luck.
The full question is
Total verbal expression ( 6,6)
When I googled this phrase lots of religious sites come up, re prayers etc, I can only find a prayer plant, which obviously does't quite fit the clue. I will keep working on it.
Many thanks.
I like Marsh's answer and it is most probably what the quiz-setters are looking for. However, it is an extremely loose clue, if so! Certainly 'tongue' in the sense of 'language' might be considered a 'verbal expression', but how can 'adder's' conceivably mean 'total'? (Yes, I know that 'add' and 'total' are synonyms but 'adders' and 'total' aren't!)
