You also can add the ContextMenu to any visual child in the data template, for instance:

<HierarchicalDataTemplate x:Key="CountryTemplate" ItemsSource="{Binding Path=Country}" ItemTemplate="{StaticResource CountryTemplate}">
    <StackPanel Orientation="Horizontal">
        <StackPanel.ContextMenu>
            <ContextMenu>
                 <MenuItem Header="Header" Command="{Binding Command}"/> <!--This command should be in the data context (each country item)-->
            </ContextMenu>
        </StackPanel.ContextMenu>
        <TextBlock Text="{Binding Path=RootName}" Style="{StaticResource TreeTextStyle}" ToolTip="{Binding Path=Description}"/>
    </StackPanel>
</HierarchicalDataTemplate>
