About
Quercus trojana, the Macedonian oak, is a medium-sized tree to 20 m producing grey-green, toothed leaves. Semi-evergreen � only losing its leaves in the coldest winters � it presents a distinct, airy appearance in winter with a mix of retained green leaves, yellowing leaves and bare branches. Large acorns more than half covered by a shaggy, grey-green cup are produced. A distinctive and ornamental oak for a well-drained, sunny garden.
