I have a few Youtube videos that I like to play at night while I'm winding down from a bit of burglary and getting prepped for sleep.

The one I was listening to tonight is "Lord of the Rings Online Full Soundtrack 2020 Pt. 2" and it's 7 hours of Lotro game music.
There is a screen shot at about 1:21:00 (one hour and 20 minutes in.) that shows a horse grazing in what looks like a cultivated field of Pipeweed.
The in-game Pipweed that Farmers can grow looks exactly like this...well actually, almost all of the crops look the same...But anyway, I noticed long ago that these fields of leafy, flower-topped plants looked an awful lot like Hemp plants. I have noticed this before and that screenshot triggered that memory and got me wondering....

Did the hobbits use the whole plant? Flower-tops and all? Or did they somehow harvest a ripe crop and avoid mixing in the tops?
Did they use the tops for some of the "specialty" Pipeweed?
