Some of these are common weeds; others are important crop plants such as corn and wheat. These annual grasses live for a single growing season and die. They are genetically programmed to die at the end of their growing season. Our common lawn grasses are usually perennial grasses. That means that they grow for several years. However, during cold or dry weather, they may become dormant (or quiescent) and appear to have died. The crown of the plant (where the leaves and roots meet) remains alive but dormant. As long as the weather is unfavorable, they remain dormant. Our lawn grasses regrow from the perennial crown. So, these haven’t really died. Finally, some of our perennial grasses die during the winter. They are not supposed to die, but due to damage from insects in the autumn or improper irrigation in the w
