Senecio thapsoides is a characteristic species of coarse limestone screes at 1300–2200 m from Taigetos to the area of the Katara Pass, with a somewhat dubious record also from Mt Chortiatis near Thessaloniki. The description was based on specimens collected by Aucher-Éloy (c. 1836) on Mt Dirfi, Evvia. Similar plants from Albania and Dalmatia are of uncertain status, being sometimes regarded as a separate species and sometimes as S. thapsoides subsp. visianianus.
