This booklet was first produced in 2005, authored by Hans, Annie & Mark Wapstra with Louise Gilfedder. Since then, the content has been kept up-to-date by Hans & Mark Wapstra (and in recent years by Mark) with changes in the Tasmanian Herbarium’s Census of Vascular Plants of Tasmania reviewed annually. New/altered names are provided direct to the Department of Natural Resources and Environment Tasmania’s Natural Values Atlas. However, numerous people have requested a hard copy. While we recognise that there will always be changes, this edition reflects the contemporary state-of-affairs and should remain relatively stable for most species for a long period.

This booklet, which was first produced in 2008, is now at its 5th edition (2026). It provides a species-by-species account of the flowering times of all of Tasmania’s native orchid species (and its one naturalised species) in an easy-to-read format (A4). Guidance on the peak and shoulder flowering period of each species is provided on a half-monthly basis, with notes given on variables affecting detectability in the field (such as weather conditions and fire regime).
