Thank you,
@Bron.
It does not matter that some of the plants are not registered and yes I would be interested in information from the southern hemisphere and everywhere else.
Right now there are no particular cultivars that I would be particularly interested in. Trying to understand daylily biology relies on getting information from as wide a range of plants as possible.
However, there is something specific I would ask you about. You may have had years without any frosts (perhaps also years where the temperatures did not go below 40F/5C). Did you have any specific cultivars that did not flower in those years (where the lack of flowering could not be obviously attributed to something else)?
I would ask for the same information from anyone else who grows daylilies in areas that are frost-free at least some years. Were there any cultivars that consistently did not flower in those years?
