Japanese Holly Hoogendorn Pollination Information

Japanese Holly Hoogendorn is a cultivar of Ilex crenata, commonly known as Japanese holly. It is a dioecious plant, meaning male and female flowers develop on separate plants. Therefore, for pollination to occur and for berries to develop, both male and female plants must be present in close proximity.

The male plants produce small, inconspicuous flowers in the spring, which release pollen into the air. The female plants produce larger flowers, followed by the development of berries. To ensure pollination, it is recommended to plant one male plant within 50 feet of several female plants. The male-to-female ratio should be about 1:5.

Japanese Holly Hoogendorn is commonly used as a hedge or border plant and attracts birds with its berries. Proper pollination ensures a healthy plant and abundant fruit production.
