No frost or snow for me last night, but it did get down to 34 degrees.
I am looking out the window and I have blooming:
petunias
kniphofia
california fuchsia 'Mattole Select' which are hardy here
annual salvia in planters red, violet
bidens
jethro tull coreopsis
coleus
begonias
some little white flower in a planter
Rozanne geraniums
Eccremocarpus scaber (hardy for me)
snapdragons (hardy for me, and some of these are volunteers)
cosmos
there are more but that is just what I see!
