Wanted: Chinese Foxglove seeds

Hello All--
Would anyone happen to have some Chinese Foxglove (Rehmannia elata) seeds that they would consider trading me? I want to try these in my gardens. A friend told me about them but I have been unable to obtain any seeds for them. Please contact me if you might can help me on these seeds. I will try my best to find some seeds to interest you in trade. Thank you! :)

I am expecting some from England, but they are at this time over due... I bought them Dec 20th through Ebay.

I am interested in an AFRICAN foxglove.

Also, this would be my first trade... so I am embarrased to ask but how many seeds do you need? I only need 2 or 3

Chinese foxglove is incredibly invasive, I had to rip it all out of my garden a few years ago.

I have South African foxglove, abbyflower fyi. Wanna trade?

Gerris2, I live in the country so invasive is not a problem here. I want to try both the Chinese and the African foxglove here because regular foxgloves do so well in my gardens and are so pretty in the country cottage setting. I appreciate your info tho. :)

CB,
if you are not able to trade for the Chinese Foxgloves, you can find them here.
