I use the Latin interchangably. Around fellow students I use it, but with most customers I don't coz like you said, they go Huh? I dont like to make anyone feel bad that way, however at the talk I gave on Sunday I did touch on the Latin and what it means to native plant seekers so that they can ensure that they are gettting the right plant since many plants have several common names.
I love that U. sessilifolia. I have it growing in my yard, its so cute!
Oji,
I didnt see Galearis spectabilis in any of my field guides. I am glad you know what it is. I had never seen it before. But it was growing right there with the Listeria. Perhaps they grow in community and finding one could be a red flag the other is near. Just perhaps...
