Finally, at the end of year 2018 I managed to edit a final screening version of the Helsinki tree calendar performed and recorded in 2017, partly spurred by my wish to finish the Stockholm Tree Calendar by the end of the year, summarized in Swedish here. The Helsinki Tree Calendar was something I began on impuls, trying to connect my old (still on-going) project of talking trees with the then new project Performing with Plants. I made several versions of some of the trees, and had serious trouble in finding some of the so-called trees in the Celtic tree calendar, like the ivy, in Helsinki, so I made some adaptations. Here comes a list of the versions I chose for the screening compilation and the installation version, as they are actually meant to be shown as a calendar, one at a time, with duration and day of recording added:
