Great photos and very informative information, my Dear friend @Siggjo. This gave birth to several thoughts. This is strange, but I know few trees that have two sexes. Only poplar, birch, mango, willow, cornel, kiwi, or actinidia come to my mind; perhaps I knew something else, but I forgot, it seems that apricot is two sexes. These trees are directly dependent on bees and other insects that pollinate inflorescences. In nature, everything is provided, but man tries to reshape everything for himself. About ten years ago, I did not hear about tomatoes and cucumbers that do not need to be pollinated, now they are. At the same time, people are sounding the alarm that the bees are dying out, but nobody says what kind of chemistry people pour under these hybrids and what nectar the bees have to carry as food to their offspring. I hope that no one will come to mind to grow a hybrid of willow, which will not be able to please us with such a variety of spring inflorescences.
