drooping sheoak reproduction

Apiaries are also recognising the value of these trees for honey, as the honey bees are greatly attracted to their pollen. Male trees produce tan-coloured strings of ‘beads’ which hang down from the ends of the branches, whereas the female flowers are more like small orange-red rounded tufts – generally situated along the branches, which hang well out – presumably to catch the wind-borne pollen grains emitted from a nearby male. A plant species long term survival depends on successful reproduction and an adequate diversity of genetics. Fruit‐set values for 447 species of plants were examined for variations due to compatibility, breeding system, life form, latitude, type of fruit, and type of pollination. Traversing through any cluster of She-Oaks, one will notice a delightful blanket of needles carpeting the ground beneath. The abundant, highly-branched twigs are excellent for absorbing wind.
