I have some E. 'Gateway' but it is a bear to dig/ divide, and i'm not sure if the early fall will work, but I can try just before the trade.
I tried to dig last spring and only managed to break off the tops of still underground stems--the roots were somewhere really far down.

Judy,

How about some fresh seed?

Jim

I'll bring a seed head, too, but good luck, I've not had any seeding around from this plant.

The price is right.

Thanks,

Jim
