Dear 
Child,
Were there not AAwtK, and were the Lonely Star not sailing off on her final leg, I bet you and I could have a wonderful discussion about this. Indeed, I hope we shall once our present commitments are done. 
For now, I offer you this image, for I am well aware of Tolkien's statements about watching Edith dance. That famous illustration of Luthien dancing is one I would love to use for "Bethberry", had it not of course already been 'taken' for Luthien. 
This image is large, I'm sorry to say; also, I must thank 
Turambar for showing it to me months and months and months ago. Indeed, at the time, I even attempted to identify the plants.
Bethberry
