Like many of the Prunus serrulata varieties, 'Ukon' was introduced to western gardeners in the early part of the 20th century. The double white blossoms, appearing in lavish profusion, are accented by the bronzy foliage. These wide-spreading trees grow to 25 feet. Flower color ranges from nearly white to pale pink. Seeds of this weeping variety were brought from Japan around 1862 by plant hunter Philipp Franz von Siebold.
Flowers are faintly fragrant.
A hybrid between P. subhirtella and P. sargentii , this tree bears clusters of three semi-double, pale pink flowers that open from dark pink buds in early spring. This variety has a most distinctive growth habit. Thought to be a natural hybrid raised from a seed sent from China by E.H. Wilson in 1907. Its glistening bark tinted dark brown and fleshy amber-red fruits are its chief characteristics. Single flowers, borne in clusters of three or four, are pink.
