Monica, I'm sure you realize that this thread is over 6 years old?
I think your best bet to trace down as many of your Moldovan daylilies as possible is to contact Mike Anders
@mfanders directly, since he's the originator of this thread. You can "tree mail" him privately on this forum using the little blue envelope at the top right of the screen.
Even if the garden is no longer being maintained, he will very likely know where many of the daylilies from it have gone. He even gives his address at the end of his initial post, so seems like he won't mind being contacted by snail mail if this attempt fails through NGA.
That being said, there are so many thousands of daylily cultivars, but the best ones do carry on for many years. People keep them in their gardens, and pass divisions along to family and friends. The problem becomes "do we know the name of that one I got from Aunt Mary?"
I see in a post above that
@Avedon had Turkish Turban as one of her favorites back in 2018 and she is still active on this daylily forum. Also
@Dennis616 found 3 cultivars listed online for sale above.
