Can only eat hemp seeds

So I saw hemp seeds in the game and thought it was cool. Was less impressed when I figured out you could only eat them and nothing else. What gives?

  1. Acquire a hoe.

  2. Stand over grass or dirt and apply the hoe.

  3. Make sure you have the seeds in your inventory.

  4. Step aside and interact with the mound of dirt you have created.

  5. Select the seeds off the menu that pops up.

  6. Your seeds should now be planted, and the dirt mound # should turn into a ^ which indicates that the square has been planted.
