Following its rejection of the proposal in 1st reading in April 2014, the European Parliament has asked the Council of Ministers to withdraw in a letter by the European Parliament president dated 11 September 2014.
Campaigner Graham Spencer said: "The proposed regulation has been withdrawn by the Commission at the request of the President of the European Parliament after the rejection of the first reading.
"That document is from the European Commission’s Work Plan 2015 – the list of legislation they will be working on and that particular document is the list of legislation that is being withdrawn.
"I’m currently discussing with other people involved with this what this official withdrawal means and what might happen next."
HTA advisor David Brown said: "We are now waiting to see what the Commission comes up with next, as they will need to propose something."
Defra head of varieties and seeds policy Andrew Mitchell said: "We have no information at this stage about alternative plans and how the Directorate-General for Health and Consumers sees the consequences."
The RHS said it was monitoring future developments.
The European Parliament had rejected the proposal, which could have meant £500 fees to register plants and led to reduced choice of plants in garden centres, by 650 votes to 15.
HW exposed the issue in September 2013, which led to a media storm and horticulture organisations taking up the issue.
