This week’s mystery seeds are also black, and seem to have two marks. They are about the size of a watermelon seed.
I found these on the ground at a gourd show, but the plants they grow into are not gourds. Can you guess what fascinating plant these seeds are from?
Edit: The answer is now posted.
Did you ever find out what these were? I have that exact seed staring at me on my desk taunting me.
I’ve added a link to the answer post so I don’t give away the answer here 🙂
