betula pendula

• Slender deciduous tree
   
• Up to 30m tall
   
• Smooth, silvery-white bark that develops deep, dark fissures with age
   
• Oval leaves have double-toothed serrations along edges and neither leaf stems nor leaves are hairy (that’s downy birch).
   
• Male catkins are long, drooping and yellow
   
• Female catkins are slender, green and are upright when flowering, drooping in fruit

The gherkin-shaped fruiting catkins turn brown in winter and, helped by birds, release tiny winged nutlets
