What is a common sedge weed found in Iowa's turfgrass settings?

Yellow nutsedge is frequently found in Iowa's turfgrass settings and is characterized by its triangular stem, yellow-green leaves, and a propensity for rapid growth compared to surrounding grasses. It thrives in moist, poorly drained soils, making it a common challenge for turfgrass managers.

Its tubers, which can remain dormant in the soil for long periods, allow the plant to persist even after attempts at removal. Understanding the life cycle and growth habits of yellow nutsedge is crucial for effective management strategies, making it an important weed to identify. The other options, while related to various plant categories, do not match the specific characteristics and commonality of yellow nutsedge in Iowa's turf environments.
