An heirloom variety from Russia. Seeds sent to Tatiana Kouchnareva by Marina Kirishcheva, Bryansk region, Russia in spring 2013. This variety came from a Russian gardener Sergey (nickname ‘Serega’), hence the name. Introduced by Tatiana’s TOMATObase Seeds in 2014. Indeterminate, regular leaf plant produces large yields of 10-14 oz., large, red, irregularly shaped fruits (some are almost heart-shaped). Excellent well-balanced flavors.
