Ruralite wrong to ditch large pot plant (7)
I believe the answer is:
etruria
'pot plant' is the definition.
(Etruria Works, plant which made ceramic pots)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for etruria that I've seen before include "Ancient country in Italy" , "founded by Wedgwood" , "Roman name for Tuscany" , "Wedgwood 1769 factory" , "Ancient area of Italy" .)
