It can be found mainly on wet, low land places of east and central part of the country. The leaves resembles strongly to Iris genus, but were much too large for other options of wild species of this genus, which grow in Slovenia. I thought that the leaves had to belong to some garden plant, which escaped into wild. This was quite probable since the place was a kind of semiruderal terrain and not far from the nearest houses of town Bovec. Only later, after seeing fruits and flowers, we realized that it is indeed Iris pseudacorus. This find was the first and is, even today, the only known place where it grows wild in northwest Slovenia.Protected according to 'Uredba o zavarovanih prostoiveih rastlinskih vrstah'Ur.l.
