Hazel

 

For the last few weeks, when touched by the winter sun, woods, hedgerows, roadsides and parks have been lit up by the yellow-gold of the Hazel catkins that seem to appear anytime from early February to April.

The male catkins are long and yellow, but the female ones are just tufts of red stigmas which sprout   from the leaf buds of the twigs and generally go un-noticed.

In the autumn, clusters of green nuts appear, which gradually ripen to a hard brown and these nuts are a very attractive food to large birds and various mammals. Try collecting some mature nuts which often scatter the ground around Hazel trees. Some will be intact, but others will have been opened and careful observation of the teeth marks around the broken nut, will indicate what creature has broken and eaten the tasty centre within the hard, brown shell.

Hazel branches are very flexible and are used for many things such as baskets, boats and houses.

Slender rods are obtained by coppicing, whereby the branches are regularly cut back to ground level so that the plant produces long, straight rods.
