Some plants have antifreeze in their roots. When winter rolls around, the liquid between a plant's cell walls can freeze, breaking its roots in the process. But plants like alfalfa have multiple secret weapons like turning starch into antifreeze sugar. Those extra sugars then interact with each other, forming a kind of barrier in the space between the cells.
This, along with other tactics can help the root trap some of the water, while limiting its transformation into ice crystals. Adding extra sugar also keeps the liquid's freezing point just a tad lower, so that water cools down, but not to the point of making damaging ice crystals.
And doing all this damage control takes a ton of energy, which is one of the reasons you don't see as much growth during the winter.
