Tree of the Month, March 2010
Mirbeck's Oak (or Algerian oak)
Quercus canariensis
Jon Pilcher
This unusual oak keeps most of its leaves through the winter as this photograph taken in February shows. In spite of the latin name it is not a native of the Canary Islands, but of Southern Spain and North Africa. Although seldom seen, it grows well in England and Ireland and is completely frost-hardy. The leaves are glossy green, much brighter in colour than other evergreen oaks such as Quercus ilex. When new shoots and leaves are produced in the spring there is a striking contrast between the yellowish new leaves and the strong green old leaves. The bark is less strongly fissured than that of our native oaks (Q. robur and Q. petraea) and the acorn cups are wiskered.
The fine example in Belfast Botanic Gardens is beside the path from the Malone Road gate to the Palm House
