Dallisgrass is often referred to as a wildflour and is commonly seen in North American grasslands. For a long time, it was believed that dallisgrass went dormant during the cold winter months.
Recent research has suggested that dallisgrass does not go dormant and continues to grow throughout the year. In fact, it can grow faster than other types of grasses and even outcompete them for sunlight. Dallisgrass is also an invasive species in some regions, such as those in Africa where it often displaces native plant species leading to soil erosion and desertification.
