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 fasciculated storage organs can reach the size of a fist already.
I've not yet attempted to try out the vegetative propagation via root cuttings (fascicles) but if this worked, it could be a solution to overcome the exhausting generative propagation.
