Pollination Information for Sky Pencil Holly (Ilex crenata 'Sky Pencil')

Sky Pencil Holly is a cultivar of the Japanese holly (Ilex crenata) and is commonly used as a hedge plant or as a vertical accent in landscapes. It is a dioecious plant, which means that male and female flowers are produced on separate plants.

The male Sky Pencil Holly produces tiny yellow flowers in early spring while the female plant produces inconspicuous white flowers at the same time. To produce berries, you need both male and female plants. The pollination process of hollies is carried out mainly by bees, flies, and other insects attracted to their flowers.

In order to get fruit or berries, you need to have at least one male Sky Pencil Holly plant for every five female plants. The berry production of the female plants can vary from one year to the next, depending on the availability of pollinators and growing conditions.

It is also important to note that Sky Pencil Holly can also be propagated by cuttings or tissue culture. This allows growers to propagate plants that are genetically identical to the parent plant, making it easier to establish a hedge or a uniform planting.
