The Summit cherry variety, developed in Canada, has become popular in Europe due to its large, flavorful fruits. Miroslav Sitarek, a scientist at the Institute of Horticulture in Poland, highlights the variety's wide heart-shaped fruits and vigorous, easy-to-form trees. The Summit variety is known for its frost resistance and disease resistance, but its harvest period is limited to 5-6 weeks due to the quick softening of fully ripe fruits.
