Just a quick note, if you just want to propagate the oregano you can just pull up some of a plant with roots and plant that somewhere else. I planted a few oregano plants 6 years ago and it comes back every year. It’s a little invasive and reseeds itself.Yes, the seed heads. I haven’t cleaned out or packaged up most of the seeds yet, I’ll probably keep putting that off. Some of that is just me being lazy but I don’t need them packaged right away, they’re not all finished and I have enough fall stuff to keep me busy.
