Aristolochia iberica constitutes the most widespread species of the Caucasian-Pontic pontica-complex. Although the propagation via seeds is more or less a disaster (stratification times up to 4 years!) it will grow very quickly as soon as established and capable of doubling the size of the tuberous stem each year.

After 3-4 years the irregularly shaped storage organs can reach the size of a fist already.
