Tibetan tree peony propagation question
I have a Tibetan tree peony that I got from Raintree Nursery about 5 years ago, and it is abut 6' high now. I have had wonderful yellow blossoms for the last couple of years, and this year, after it flowered, it has put out large numbers of pods about the size of my thumb. The pods are still green, but I broke one open and it has large yellow seeds about the size of a small marble. When is the best time to collect the seeds and what are the steps for propagating them?
