As a SC native, I'm trying to figure out what this plant is.

[raccoon]

I have noticed this time of year, late summer and early fall, a plant that grows in the ditches and low areas in the South Carolina low country. It is some kind of a grass. It is probably about 4 feet high and it has a head like wheat only it is rust red.

Can anybody help me with this?

1. There's an app for that.

I have Pl@ntNet on my phone.

And good morning.

2. Seek is another app that will identify it

I use Seek all the time to identify plants, bugs, mammals, shells, etc. it’s free and is privacy-focused.

3. PlantSnap

... is another app for Android and iPhone.

Good luck!
