Bromegrass is considered less prone to injury from cold weather compared to wheat and alfalfa due to its resilience and adaptability to cooler temperatures. This grass species is well-suited for northern climates and has a robust growth habit that allows it to withstand harsh winter conditions more effectively than many other forage and cereal crops.

When exposed to low temperatures, bromegrass can enter a dormant state, which protects it from cold stress. Its deep root system also enhances its ability to access moisture and nutrients, contributing to its overall health and recovery in spring. In contrast, species like wheat and alfalfa may be more susceptible to winterkill or frost damage due to their specific growth requirements and sensitivity during the winter months.

The other grass options may have certain cold-tolerance characteristics, but bromegrass is particularly noted for its hardiness and ability to thrive in cold environments, making it the ideal choice for situations where cold weather poses a risk to crop survival.
