I thought of your garden when I went outside yesterday. Our snow was largely melted, though there was still some on the trees, bushes and grass. I noticed that any flowers touched by the snow were wilted and dead.
BUT...
Interestingly, one neighbor has geraniums in a planter on her porch, which is covered by a little awning, and they're still blooming brightly! Another has impatiens in a hanging pot, and they're fine, too. I was amazed that they survived. Both plants looked like it had never snowed at all.
