There's some sort of grass or weed that grows on the sides of my
driveway. My cat's love to play with them and I'd like to figure out
what exactly they are.

They look like wheat but I don't think that's what they are unless it's
some sort of wild wheat. They're usually green but are now turning
yellow/light brown and drying and dying out. Many people I know refer
to them as cat tails but that's not what they are.

Does anyone know what they might be?
