Oltenia is a region located in southwestern Romania and it is characterized by great climatic, pedological, geomorphological, and floristic diversity. In this part of Romania, many southern elements find their habitat, some of them being rare in the flora of the country (e.g., Cirsium creticum). Climate changes in recent years have led to obvious changes among plant taxa, both in terms of distribution in nature and especially in their phenology. For some taxa, these changes led to the widening of the area (e.g., the psammophilous elements: Erodium hoefftianum subsp. neilreichii, Mollugo cerviana, Bassia laniflora, Achillea ochroleuca, Salvia sclarea, Silene borysthenica, Limonium tomentellum, Polycarpon tetraphyllum, Hordeum bulbosum), while for others on the contrary, to its restriction (Aldrovanda vesiculosa, Pisum sativum subsp. elatius).
