The first plant that everyone thinks of as a producer of red berries around Christmas time is the holly bush. It’s an obvious choice but getting holly to produce berries is more tricky than one might think. Firstly, it needs to be a female plant, these can be identified when the plant is in flower as the males have a more prominent stamen.
Secondly, the female plant also needs to have a male plant in close proximity to it in order to ensure cross pollination. Only then will the female plant produce the winter red berries that everyone wants to forage for their Christmas wreaths. Although beautiful and festive, the berries of holly are toxic to humans when consumed but there are plenty of other winter red berries that aren’t.
