Clustered around the small hut that used to offer refuge to the Cambridgeshire constabulary policeman on duty in the Garden, are some elegant hazels.
One of the earlist to flower is Corylus avellana 'Schizochlamys', which is producing long catkins in pale mustard yellow with a pink flush in generally two-tailed tassels.
These catkins are the male flowers, the hazels being monoecious and wind-pollinated. No sign yet of the tiny female flowers, which are barely visible - only the bright pink styles protruding from a tight bud, like miniature anemones.
