Kurogane Holly

The Ilex rotunda, or Kurogane Holly, is an evergreen tree of southern China, Japan and Korea, densely crowned and glossy-leaved, that spends autumn and winter loaded with small bright red berries. Female trees carry the fruit; a male in the vicinity is needed for a full set.
It grows to 5 to 15 metres with a naturally rounded, even crown, which is why it is used as much for formal avenue and courtyard work in East Asia as it is for its winter colour.
The Kurogane Holly gives a dense evergreen crown year round and a heavy berry display through the months when a scheme has least to offer.
