The majority of the trees at Posteljooninpuisto are deciduous.[3] Trees planted there include common lindens. All of the lawn areas, structures of walking paths and lights were renovated from 2017 to 2018. At the same time, a pool was built underneath the park, in order to prevent urban runoff water from draining to the tunnel underneath the railway.[6]
The steel sculpture Elämän virta ("Flow of life") designed by Aimo Taleva is located at the park. It is a memorial to the schlager and tango singer Olavi Virta, who lived his final years in Tampere.[4]
