Snow is something Montanans have plenty of. Fluffy snow provides good insulation for plants and keeps the air temperature beneath it from dropping to dangerously low levels.
Snowflakes capture nitrogen in the atmosphere and bring it down to the soil.
It isn't much, about 1 pound of nitrogen per acre of land, but every little bit helps. In addition, snow protects low plants and the lawn from drying winds and thus decreases some winter damage. It depends on where you are. Soils with pH above 6 keep the flowers pink. Lower the soil pH below 6 and soil aluminum becomes more available, turning flower color to a faded blue.
