Winter cherry – Prunus subhirtella Autumnalis Rosea
A peculiarity in our latitudes is the ornamental cherry Prunus subhirtella “Autumnalis rosea”, also called snow cherry or autumn cherry. Our specimen is a good 15-year-old high-stem, which reliably supplies us with flowers from November.
The plant hormone responsible for decelerating the flower buds of all spring flowering plants is very weak here, and so a few cold nights with subsequently milder temperatures are enough to trigger the pre-flowering. Hence the denomination: autumnalis = autumnal. Depending on the temperature of the winter, the ornamental cherry tree flowers continuously until March / April, the main flowering follows.
