Description

Ilex x hoehneana is a broadleaf evergreen holly that grows up to 20 feet or more, depending on location. Its pyramidal form is compact, dense, well-shaped, and pleasing to the eye.  The dark green leaves along with the brilliant red berries add to its attractiveness. Locate in an area that is protected from cold winter winds and hot summer sun.  

'Martha Berry' ranks among the best of the species.  It is a female, requiring a male pollinator to produce fruit.  

Insects, Diseases, and Other Plant Problems:  Not as cold hardy as 'Nellie R. Stevens'.  Insects that may affect this plant are holly leaf miner, spider mites, whitefly, and scale.  Leaf drop and leaf scorch may be an issue.  Yellowing of the leaves due to high pH soils can also affect the plant.
