Circa 2007 my wife brought home three daylilies, and I dutifully planted them to mark the grave of our beloved dog, Suzy. One died but the other two soldier on, Stella D'Oro and Pardon Me. Stella has been moved at least twice and now resides in a planter on our deck. Pardon Me, however, still resides in its original location, and was joined by a new addition, circa 2014. Together they produced a prolif and a number of seedlings. As of this writing they are still blooming, although only one or two blooms a day. The seedlings and prolif are about done but the original plants still have about four buds left. :)
