This is a gentle snow. Temperatures are cold and getting colder, so this is not the sort of snow that threatens to bend and break branches. It accumulates on branches of evergreens, trapped by dense needles, but even the tall stems of nandinas (Nandina domestica, below) do not arch under the slight weight. Reports are that it is no picnic to be driving about in, but it is not a bother to the garden.
With nights forecast to fall to a bit below ten degrees there is little concern over the fate of evergreens, or the few marginally cold hardy shrubs that survived last winter’s lows. Certainly these will have no problems as along as temperatures remain above zero.
There is some small concern over the gardenias (Gardenia jasminoides). These are the supposedly cold hardy ones that all died last winter, but were planted again in an act of faith that temperatures will not again venture much below zero.
The flowers of mahonias (Mahonia x media ‘Charity, above) and Vernal witch hazel (Hamamelis vernalis, below) will have no problem with this cold. When overnight temperatures dropped below zero last winter these remained in bloom, so a few nights of cold will not bother them at all.
