A petition with almost 3,000 signatures has been put together on behalf of Angela Darnley. Her daughter Jenna died back in 2008 and was buried in St Michael's church yard in Grimsargh, Lancashire.
The church, which follows specific regulations put forward by the Church of England, says the flowers and memorial need to be toned down in order to ensure fairness for everyone who uses the grave yard.
It also says a number of complaints have been made.
Speaking about the case, Archdeacon Michael Everitt from the Diocese of Blackburn said: "I sympathise with Mrs Darnley but the Diocese of Blackburn, of which St Michael's is a part, in common with all other Church of England Dioceses has very specific regulations about what can and can't be placed in our churchyards and which people who bury loved ones in our churchyards are made aware of.
"So the Vicar and churchwardens have a legal responsibility to preserve the churchyard as a well-ordered place for every family whose loved ones are buried in the churchyard.
"The regulations exist to ensure fairness for everyone and to prevent unrestrained growth of memorials on and around graves."
Since the petition was launched online the vicar and churchwarden at St Michael's met with Mrs Darnley to propose a comprise and is awaiting a response from her.
