Digging Mertensia

I want to send some M. virginica to a friend. When is the best time to dig, when summer-dormant or wait until fall?

While I'm no expert, my guess is shortly after flowering when the plant goes summer-dormant... giving the plant sufficient time to get re-established on the recipient end.  Your question reminds me, that my plant of this did not come up this year :(  It's like an old friend, one of the first plants I grew as a young boy at 10 years old, 45 years ago  :o, and I still love this spring ephemeral plant.

Nothing to add from me, execpt,

Welcome to the forum, Plummer!  We hope to hear more from you!

I agree with Mark that the best time is right before going dormant. I would go with the younger smaller plants as the taproot can get pretty big.
