All 14 of the borough’s open spaces entered for the award hoisted a flag while two parks earned additional awards.
Tam O’Shanter Urban Farm received a Green Flag Community Award recognising spaces managed by voluntary and community groups.
Meanwhile Birkenhead Park retained its Green Heritage status in addition to its Green Flag.
Councillor Ellis praised work of parks staff, officers and Rangers but also singled out the work of volunteer friends groups.
"Gaining these awards year on year relies on the involvement of community representatives in the management and development of the parks.
"Staff, volunteers and friends groups representing Wirral’s winning parks have played a key role in achieving this success. It is fantastic."
One of the green spaces, Hilbre Island Nature Reserve, is home to the only island in the United Kingdom to boast a Green Flag.
Two new winners of the Green Flag this year were the North Wirral Coastal Park and Meols Park.
Other winners included Ashton Park, Thornton Hough Village Green, Coronation Gardens and Brotherton Park and Dibbinsdale Local Nature Reserve.
