Scientific Name: Ilex x 'Nellie R. Stevens'

Pollination Information:

Nellie Stevens Holly is a hybrid cultivar of holly produced through cross-pollination. It is essential to have both male and female plants of this cultivar for successful pollination and subsequent berry production.

Male Pollinators:

• The male holly plant used for pollination can be any variety of Ilex x 'Nellie Stevens' or any other holly cultivar.
• It is important to ensure that the male holly flowers around the same time as the female Nellie Stevens Holly to facilitate successful pollination.
• Planting at least one male holly plant for every five female Nellie Stevens Holly plants is recommended to ensure a good fruit set.

Pollination Process:

• Pollination of Nellie Stevens Holly occurs through the transfer of pollen from the male flowers to the female flowers.
• The wind or insects, such as bees, can help in the pollination process by carrying the pollen between the flowers.
• It is advisable to plant the male holly plant(s) within a close proximity to the female Nellie Stevens Holly plants to facilitate the pollination process.

Berry Production:

• Once pollinated, the female Nellie Stevens Holly plants produce vibrant red berries.
• The berries are a popular attraction for birds, adding wildlife interest to the garden or landscape.
• Berry production can vary depending on the availability of male pollinators and the overall health and condition of the plant.

• Dig a hole that is twice as wide and just as deep as the root ball of the plant.
• Gently remove the plant from its container and loosen the root ball if it appears to be root-bound.
• Place the plant in the hole, making sure it is at the same level as the surrounding soil.
• Backfill the hole with soil, firming it gently around the roots.
• Water the newly planted holly deeply to settle the soil. Add a layer of mulch around the plant to help conserve moisture.
