Densa Inkberry Holly (Ilex glabra 'Densa')

Pollination Information for Densa Inkberry Holly (Ilex glabra 'Densa')

The Densa Inkberry Holly (Ilex glabra 'Densa') is a versatile evergreen shrub known for its compact growth and glossy black berries. It belongs to the holly family, Aquifoliaceae, and is native to the eastern United States. Pollination Requirements: Unlike many other holly species, the Densa Inkberry Holly is self-fertile, meaning it can produce berries without needing a separate male plant for pollination. It has perfect flowers, which means they contain both male and female parts, allowing for self-pollination. Pollination Method: The Densa Inkberry Holly is primarily pollinated by bees, including various native bee species and honeybees. These insects are attracted to the flowers' nectar and inadvertently transfer pollen from the male parts (anthers) to the female parts (stigmas) of the same flower or other nearby flowers. Flowering and Berry Production: The Densa Inkberry Holly typically flowers in late spring to early summer, usually in May or June. The small white or cream-colored flowers are clustered on the branches and have a pleasant scent, attracting pollinators. Once pollinated, the flowers give way to green berries, which turn black as they mature. Benefits of Pollination: Pollination ensures the production of berries, which are a valuable food source for wildlife. The black berries of the Densa Inkberry Holly persist through winter, providing sustenance for birds, such as robins, cedar waxwings, and thrushes. Additionally, the flowers contribute to the overall beauty and aesthetics of the plant. Pollination Tips: To enhance pollination and berry production in your Densa Inkberry Holly:

• Plant multiple Densa Inkberry Holly shrubs close together to promote cross-pollination, although it is not necessary for fruit production.
• Ensure the presence of bee-friendly flowers in your garden to attract pollinators.
• Avoid using pesticides during the flowering period, as they may harm pollinating insects.
• Provide adequate sunlight and regular watering to maintain a healthy plant, as this can positively influence flower and berry production.
