Description

Ilex x aquipernyi, or Aquipern Holly, is a hybrid cross of I. aquifolium and I. pernyi. Aquipern Holly is an evergreen shrub to small tree, densely narrow and pyramidal in form, and grows up to 20 feet tall. Hollies are dioecious plants so you will need both a male and female to set fruit. Ilex x aquipernyi 'Aquipern' is the male clone of this plant, and Ilex x aquipernyi 'San Jose' is the female clone. This plant is considered a northern holly because it doesn't tolerate heat well. In southern climates, the shrubs appreciate some afternoon shade though the best fruit production occurs in full sun. Use this plant as a screen or hedge in a shrub border, its tall, narrow form make it a great choice for vertical spaces.

This holly is tolerant of most soils except poorly-drained ones and can be grown in full sun to partial shade with moist, well-drained soil. It is is drought tolerant once established. Prune in the late winter to control its size if needed. It likes partial shade especially in hot summers. It can grow in heavy clay and nutritionally poor or very acidic soils This plant has no serious pests.

The fruit and evergreen leaves make for winter interest in the landscape. The spiny leaves make this a good choice for a barrier or privacy screen or use as an impenetrable hedge. It can also be planted as a specimen, used in small groups, or planted along a foundation. Mature plants do not tolerate root disturbance, so it is best to site the plant in its permanent position.

Diseases, Insect Pests and Other Plant Problems:

No known diseases or pest issues, but it can be challenging to grow in the south because it dislikes hot summers and cold winters.
