The genus Arum includes approx. 29 species and is the only genus of the family Araceae with representatives reaching the temperate zone of Europe. The present study aims to bring to attention a species of Arum native to the Mediterranean area (A. italicum Mill.), in order to establish the possibility of being cultivated in Iași, in the NE area of Romania. Phenological and biometric observations of plants in experimental crops were compared with data from the literature reported for plants in natural habitats. It was found that in the conditions of Iași, A. italicum wintered in the field without protection (it behaved like a rustic geophyte), but the foliage, formed in autumn, disappeared during the summers when very low temperatures occurred and reappeared in spring (March), and flowering began at least a month later. The biometric determinations on morphological characters of decorative interest were within the limits specified in specialized bibliographic references. The results obtained show a good ability of the species to adapt to a temperate continental climate with excessive variations and can be recommended for garden decoration.
