Catkins


Temperatures are just above zero, but since last week the first Hazels (Corylus avellana) are in flower. The bushes got a light yellow hue, caused by hundreds of drooping male catkins, each several centimeters long.






















Today I found some female flowers too. Mostly they start flowering about two weeks after the male flowers, maybe to avoid fertilization with pollen from the same bush. But here the lapse was much shorter.


The female flowers are tiny, consisting of only millimetre-long sticky red pistils.
