A touch on the chill side this morning, with pretty much everything rimed with frost until the sun was able to warm things up just a little, though I think a repeat is due tomorrow morning.
These hellebores were unfazed by the deep freeze though not everything will be as forgiving, so a roll of horticultural fleece would be useful for anything a touch tender in your garden.
Opiophogon nigrescens, so-called Black Grass (though I think it is part of the lily family) looking particularly fine with the frosty coating. Bay, Wallflowers and Camellia in the gallery there too.
I think I can take off one or two of my thermal layers now, maybe a fleece and my gloves….

Absolutely beautiful photos!
Spooky – we both crafted posts with the same title and a picture of frosty Ophiopogon! http://frustratedgardener.com/2015/01/24/a-touch-of-frost/
