Cattail

Typha

Also known as: tullies. 

Also known as: tullies. 

Cattails have dense, "sausage-like," spikey flowers, called the catkins that appear on top of the long, slender stems in late summer to early fall. Cattails can be partially submerged or in boggy areas with no permanently standing water and can grow to 5 or 10 feet in height. They provide a wildlife habitat and refuge. Overgrowth can choke off open water, driving away birds.
