The phenology and yielding of lingonberry cultivars ‘Sanna’ and ‘Sussi’ in East Lithuania are described. The shrubs of ‘Sanna’ and ‘Sussi’ cultivars planted in transition mire peat during 3 to 4 years formed a dense soil cover. Their berries were larger than those of natural plants. The ‘Sanna’ and ‘Sussi’ cultivars blossomed by 1 to 2 weeks earlier than natural lingonberry, and that increased the chance of flower demages by late frosts.
