Species:koehneana

Family:Aquifoliaceae

Ilex x hoehneana is a broadleaf evergreen holly that can reach heights of over 20 feet, depending on its environment. This species features a compact, dense, and well-proportioned pyramidal shape that is visually appealing. Its dark green foliage, complemented by vibrant red berries, enhances its ornamental value. It thrives best in locations shielded from harsh winter winds and intense summer sunlight.

Among its varieties, 'Martha Berry' stands out as one of the finest. This female plant requires a male counterpart for successful fruit production.

When it comes to pests and diseases, 'Martha Berry' is not as resilient to cold as 'Nellie R. Stevens.' Potential threats include holly leaf miners, spider mites, whiteflies, and scale insects. Additionally, issues such as leaf drop and scorch may arise, and high soil pH can lead to yellowing leaves, further impacting the plant's health.
