Silver Birch produces white bark and smooth twigs with little, dark warts speckled all over. Two key things to look out for in Silver Birch are its triangular shaped, bright green leaves, and year-round, unique, silvery bark.
Betula Pendula also produces male + female catkins throughout April-May. Male catkins will appear long, with a yellowy-brown colour, hanging in groups of 2-4. Female catkins, on the other hand, are much smaller and shorted, showing in shades of bright green. After the female catkins have successfully pollinated, they will change to a darker, crimson colour, where masses of tiny seeds are produced during Autumn and scatter by the wind.
