How can you identify cattails?

Cattails can be identified by their distinctive brown flower clusters and their tall stature, typically reaching heights of 3 to 10 feet. They are commonly found in wetland areas and along the edges of ponds, lakes, and marshes. The brown flower spikes, which appear above the tall, narrow leaves, are a key feature that distinguishes cattails from other aquatic plants.

The other options describe characteristics that do not align with cattails. For instance, floating plants and those with white flowers would refer to other aquatic species, while vibrant green leaves could describe various plants but lack the specific features of cattails. Additionally, cattails thrive in wet, marshy soils, contrasting with dry, sandy environments, which isn't suitable for their growth.
