Description

Hetz Holly is a cultivar of Ilex crenata, which is a native of Japan and east Asia and can be found in thickets, woods and wet places in lowland and mountains all over Japan. Hetz Holly is a handsome evergreen shrub in the Aquifoliaceae family with a dense, rigid, and compact form and grows up to a 6 1/2 foot high rounded mound. It is a larger form of the 'Convexa' cultivar, with larger leaves. It tolerates severe pruning, allowing you to control its height.  It also tolerates drought and air pollution, poor, sandy, and clay soils, but is intolerant of alkaline soils. It does well in the shade and is easily transplanted. It has a slow growth rate and has pest problems.

Plant in the full sun to partial shade in acidic well-drained soil though it tolerates a wide range of soil types, from moist to dry, including clay. It may not thrive in areas with high heat and humidity (USDA zones 8 and 9) and may also be less cold hardy than other cultivars. The Ilex species is dioecious (meaning individual flowers are either male or female, but only one sex is to be found on any one plant, thus both male and female plants must be grown if seed is required). Because ‘Hetzii’ is a female cultivar, it will need a male pollinator in order to produce fruit. .

Diseases, Insect Pests, and Other Plant Problems:

No serious diseases or insect pests. Spider mites and nematodes are occasional pests.  Alkaline soils will cause the leaves to yellow.
