Summary Kasumizakura (Prunus verecunda Koehne) is a cherry tree, which grows wild centering on the Hidaka district in Hokkaido, however, the characteristic is seldom known. Therefore, we investigated for three years in 2000 to 2002 about the bloom characteristic of Kasumizakura. Consequently, compared with Ezoyamazakura (Prunus sargentii Rehder) currently that in Hokkaido planted, ,he bloom first day and full bloom day of Kasumizakura were late about two weeks. By planting Kasumizakura with Ezoyamazakura intentionaily, the peak of a flower is made twice and becomes possible appreciating a period longer than before. Moreover, the flowering period of Kasumizakura was about one to two weeks like Ezoyamazakura. Furthermore, for the number of the maximum bloom, although there was a remarkable difference between individuals, the individual with many amounts of bloom had many amounts continuously for three years, and the individual with few amounts of bloom had few amounts continuously for three years. From the result of bloom characteristic investigation, the individual with very early bloom time or the late individual, the individual with the very long flowering period, and the individual with many stably bloom etc. were able to select the 19 superior individuals with admiration Value high as greenery.
