Hi plantloverla. Sorry, but it looks like muellin is not native to the US. Unless there is another plant that also goes by this name.

Here is a link that might be useful: USDA info on mullein

I can send you mullein (large grey/green leaves w/ tall spires of yellow flowers) for some coral honeysuckle. Unfortunately we're getting our first real snowstorm so it probably won't be up for another month.

Hedy

I can send you lots of mein in almost all sizes from my property. Let me know if you are still interested. Happyseed

Plantloverla, if you have only ever seen one of these plants in your state in your life, then you should consider if you want to be the one responsible for introducing them to your area. Around here, muellein are pesky, non-native weeds.
