I sent in an order snail mail, but I haven't heard back, or had any email response from Mary. I ordered a lot of historics from her, and if she isn't in business this year, I would like to find them somewhere else if possible.

I don't see anything on their site that says they aren't. When did you send your order? Can you try calling them?

She is still in business. Time is taken by redoing many beds, id'ing those which grew into other clumps, updating the website, clearing some invasive weeds, and controlling some pests that like to chew on rhizomes. Many varieties are not available due to losses or short supply.
Email seems to work pretty well. A list of alternative varieties is helpful.

Thank you, Dave.

She replied to my email. It looks like I hadn't sent the one before that I thought I did. She isn't sure she has all the ones I had on my list.
