And, Re: Peonies. Root divisions from friends is how I’ve always gotten mine, though they are super-easy to grow from the rhizomes which I have done with the current four I have.
You can almost always find ‘Sarah Bernhardt’ (pale pink) at Walmart, and Jung’s, of course, usually has a great selection of potted Peonies at the stores or through mail order.
I just have the one and that’s all I want. It’s the star of the flower garden. Probably get 24 or so blooms a year. I just don’t have room for anything else.
