The tall yellow sweet clover is named Meliltus oficinalis.
The white sweet clover is named White Sweetclover (Melilotus albus).
Thanks for satisfying my curiosity, Greene. It's so satisfying to be given the answer! I went to the database and looked it up, and sure enough, Melilotus officinalis was the very plant!
It is so nice to run into my friend, the Angel
again!
All the very best to you.
