I've looked through your site and I will probably place an order in July. Am expecting a property tax refund then and will have to prioritize, but I think I will be ordering.
Meanwhile: I don't remember where I read this - probably somewhere else on ATP - but I am SURE you can tell me right or wrong: after a rhizome has made a flower stalk, it will never make another. It becomes food for its "kids" and after the first season of that, you can remove the older rhizome with a knife instead of digging and dividing the whole bed every few years.
