Hi, Jim. I don't have any of them, but a few notes.

Calamagrostis x acutiflora is a hybrid that rarely sets viable seed. You'll need to grow it from division.

You can buy E. magellanicus seed from Jelitto, in Germany. They list it as AGROPYRON magellanicum (ELYMUS magellanicus).

M.s.'Graziella' may not come true from seed. Many named Miscanthus revert to species when grown from seed.

P.s. 'Rubrum' rarely sets viable seed. It's usually grown as an annual in zones north of 9. It might be worth trying if you can find seed from a warm zone, where the season may be long enough to allow it to set mature seed. I tried it last year, and got no germination.

All that said, I started hundreds of grasses from seed last winter. Many of them are hardy in your zone. Maybe we can do a trade, grass for Hosta, next spring?

Hi Donn,
Thanks for the information, it was a great help. I'm going to give Jelitto's a try. Have you ever ordered from them?

Also, I would like to trade with you in the Spring, I have several Hostas. Some that I grew from seed and are doing great.

Jim...I ordered 17 varieties of grass from them, and one packet of Iberis. Their service is excellent. They also have a stunning and useful catalog.
