SOLUTION: The method for breeding a new variety of dogwood comprises the following process: continuously observing characteristics in chance seedling of Cloudnine (a garden variety of dogwood) grown to have a tree height of about 2 m, selecting a branches whose middle portions slanting at 25 deg.-35 deg. to the trunk at the middle portion of the stock and bearing large flowers, growing the selected one by cutting, fixing the grown one in a growing area, raising the fixed one to obtain a dogwood having branches whose middle portions slanting at 25 deg.-35 deg. to the trunk at the middle portion of each of the 6-year-old stock, and bract-containing inflorescences of 11 to 14 cm in size.
