I love the idea of shipping roots. Your prices are good, as well.
Unfortunately, my original echinacia purpura didn't make it. I think the roots were just too fragile. I had to keep them in the plastic bags for a few days after receiving due to a snow storm. They didn't make it those few days, even though I ensured they had moisture. . I did plant them just in case, but they just decintegrated.
The butterfly weed, on the other hand, started growing in the bag! They are doing very well, and thank you for adding a few extra stems.
