@Herrwood, here is a photo of my Lamb's Ear out back. It was 1-2 plants as I recall, planted Aug 2019. The spread is about 5' now.
I also transplanted around 10 bits of it to a bed out front of my house. But unfortunately, right after our snowpocalypse in 2020, our yard service had a new guy working the weedwacker who never got the memo to never to go inside my beds. He wacked it all off to the ground (we weren't home) just when it was coming back off that horrific freeze. I was devastated again. Most of it is coming back for a second time, so it's definitely a survivor. I'm going to transplant some more plugs of it this week to fill out the front bed a little faster. Love to touch the stuff and love the minty color against all the darker liriopes in that bed. I also have about 50 second season irises in that bed that are just beginning to set their bloom stalks this year, so lots of height contrast, too. )
