Cool temps followed by several days of temperatures in the mid teens has not done much to this Nerine or Guernsey lily. This plant is in my front garden and I check on it whenever I go for a walkabout and I keep thinking it going to shrivel and die off but I am amazed first at how long it has been blooming and second by how freezing temperatures does seem to faze this plant. It has been a real joy to see this plant keep blooming since the colors are so bright. Enjoy.
