The magazine is aptly named after the word used by the keen topiarist Pliny the Younger (62-100AD) to describe his most prized and skilled gardener – the European Boxwood and Topiary Society annual journal is issued free to all members of the Society. It contains a variety of articles of academic, botanical and scientific interest, as well as articles on garden design.  It has features on many exclusive private gardens, both historical and contemporary, which have been visited by EBTS members across Europe.

As evidence of the status of Topiarius, the International Standard Serial Number (ISSN 1759-0469) from The British Library was issued in October, 2008. This is similar to an ISBN for books but applies to serious journals issued on a regular basis under the same name.
