These seeds were a bit of a mystery for me.
I knew the seeds were in these button-like seed cases on the plants.
But what did the seeds look like?
I pulled one apart. Are these the seeds?
No, those are the envelopes the seeds come in. The seeds are circular and pretty tiny.
Hint: this is a desert plant that is related to hollyhocks.
Do you know what it is? Don't be shy to leave your guesses in the comments.
Edit: The answer is now posted.
