I just saw this thread, so will give my opinion about the 3 owners requirement.
It is a little disappointing when a cultivar is featured and no one posts an evaluation of the plant. There are some in the "Daylily of the Day" list that have no evaluations at all. Partly because I don't check cultivars for 3 owners any more. I trust that members here submitting a cultivar to be featured will do that. But I know some members either aren't posting their evaluations or didn't see the cultivar listed.
If we don't impose a rule about how many own the cultivar, then I imagine many people would post brand new cultivars that no one has and there again would possibly be even more cultivars listed with no evaluations.
Here is the thread for all the Daylily of the Day cultivars (except the most recent cultivars listed on the Daylily Forum):

Remember that you can post a new evaluation EACH YEAR that you own a cultivar and get another acorn. I know that plants can change over the course of time. Some do well and some don't. Positive and negative information is accepted and helpful to anyone trying to decide if a particular cultivar would be a good purchase for their area, climate, and zone.
Acorns can be used for the Not-a-Raffle Raffle to receive more daylilies (like this month with 2 vendors donating daylilies)!!! But if for no other reason, please post an evaluation of a plant to share information with other gardeners. Newly acquired plants as well as established plants can be evaluated and all info is considered helpful as long as you are describing your experience with any given cultivar.
