Hazel catkins, the male flowers of Hazel nuts, are past their best in the south, but fresh catkins, or ‘lambs tails’ as we called them as children, can still be found in Sheffield. Walking the Five Weirs Walk on Wednesday these shone brightly, overhanging the Don. As a reminder, here’s a photo, too, of some of the male flowers (catkins) and females- small, reddish and stemless, which can be found on the same bush. Conditions: Mostly sunny intervals. Temperature: Max 6- Min 1c.
