CATKINS

There are 14 trees in this guide that bear catkins in winter or in spring (before the leaves). The catkins are easy to see and sometimes quite brightly coloured, so use this option to identify these trees. Most trees bear their catkins for a short time – usually a few weeks – so the period March to May is probably the best time to use this means of identification. Some trees have male flowers on one tree and female flowers on another tree. Others, such as Alders and Hazel have male and female flowers on the same tree. Alders have catkins in some form all the year. They shed pollen in February/March.
