Cultivation
Pollinator cultivar — holly
Ilex L.
Holly is a dioecious plant, therefore, for fruit formation on female specimens, it is necessary to have a male plant of the same species that blooms at similar times.
In the reference 5 varieties crop Holly, where this is mentioned in the description.
Most holly species are dioecious plants, in which male and female flowers are formed on different specimens. For successful pollination, a male plant must be located within 15–30 meters of a female to ensure pollen transfer by insects. A key condition for fruiting is strict synchronization of the flowering periods of both sexes.
Although species compatibility is preferred, cross-pollination between closely related species is possible if flowering times coincide. There are rare exceptions, such as self-fertile cultivars like Ilex aquifolium 'J.C. van Tol', which are capable of setting fruit without the presence of male plants, as well as cultivars with partial parthenocarpy.
When selecting pollinators, it is important to consider that cultivar names may not correspond to their sex; for example, female names may be given to male clones. A single male specimen can provide pollination for a group of 5 to 20 female plants, which makes the correct choice of clone critical for berry production.
