The invention refers to a variety of balsam (small trees), Impatiens balsamina L., named Bistrita, obtained by the autopolyploidy method, followed by the repeated yearly selection of the resulted material. This variety is recommended for cultivation on sunny fields and humus-rich soils with sufficient humidity, in order to decorate parks and gardens, as well as for growing in flower pots. The invention is an autopolyploid with 22n = 154 chromosomes and a height of 35 ...45 cm, whose growth is determined by means of a loose raceme with a shrubby aspect. Its bright green leaves are elliptic-lance-shaped, opposed at the base and alternate towards the tip of the branches. The stomata have a large diameter and a high amount of chloroplasts/stomata. The flowers are fiery red, hermaphrodite, double, and have numerous white dots on their petals. They are intensely perfumed, 100 ... 200 per plant, and have the floral formula percentK53 C10 A5 G(5). The blooming period of the flowers is July - October when hoarfrost falls, and their life span is 6 ...10 days. The fruit is a capsule with seeds, where each plant has 200 ...600 seeds.
