Some of the photos submitted were from the daylily nurseries through a moderator or a member here on NGA. The nursery allows the photo here or the member visits the nursery and takes photos of a particular cultivar and posts it in the Plant Database. So they don't own the plant, but just published the photo(s) here in our database. Those members won't be able to do an evaluation.
But .... yes! you are correct that not everyone submits whether they own (have) a cultivar. So ....it's possible that lots of photos from different members means a high chance that many people could give an evaluation about the cultivar.
Either situation is possible, but it's best to choose a cultivar that has lots of photo submissions AND "have".
