October 2015 was unusually mild, 0.5°C above the long term average. This has resulted in the garden’s roses deciding to have another go at flowering. It was a risky strategy, as now we are in November we have been getting some night time frosts. However, this did make for some rather nice scenes of frosted flowers in the dark of the night.
If the water inside the plant’s cells freezes, the ice takes up more space than liquid water and will burst the cell walls. When the water liquifies again the cell contents drain, leaving a limp and damaged plant. Fortunately, on this occasion, the frost seemed to be confined to the moisture on the outside of the plants and the flowers survived. The trees, were taking no chances and have already shed their leaves!
