From Tatiana’s TOMATObase:
A heirloom tomato brought to North America from Irkutsk, Siberia. According to Andrey Baranovski of Minsk, Belarus, this tomato is originally from the European part of Russia (former Soviet Union), and it was also grown in Siberia.
Introduced to SSE by several members in the SSE 1995 Yearbook, most of them note CV Nichols Garden Nursery as the seed source. Hence it is logical to assume that this variety was first commercially offered in 1994 by Rose Marie Nichols McGee, the owner of CV Nichols Garden Nursery . According to Amy Goldman, Rose Marie acquired the seed from Kate Rogers Gessert of Eugene, Oregon in the early 1990s; Kate found this tomato in Irkutsk, Siberia, Russia.This tomato has been cultivated in the former USSR since at least the 1980s
