I have had no clue til the last year or 2 that this was not the actual registered plant. It definitely has good plant habits, grows well, blooms pretty well. It is one of the 1st daylilies I started gardening with. Probably came from a box store, but I have had it so long I don't remember. I have divided and shared it numerous times, and still have 5 or 6 clumps of it. It is in the part of the garden that has to struggle against weeds, never gets water even in droughts, no fertilizer, and still nothing seems to bother it. No matter how it started, it is a keeper, especially in those places other plants do not do well. Edited to add, when I first found out that my Bonanza was wrong, I did a search of online daylily sales, every one had this as Bonanza. I have seen it for sale locally too. At this point in time, I think it is Bonanza
