Could plants absorb ice dust from the soil?

I was wondering if plants could absorb fine ice dust mixed into the soil. That is, without a thick layer of snow on the ground, but with traces of ice in the soil.
As an extension of this, I wonder about a plant's ability to make use of such grains of ice, melting them into water and using them.
I suppose that raises the question of how the plant will generate enough heat to melt the ice, since clearly its environment is failing to melt the ice for it. Chemical thermal process, perhaps?
