Exotic Candy has been in my garden for 10 years and for the first 6 or 7 years it just kind of sat there without multiplying. Since we have a lonicera plant that needs trimming and it is very close to Exotic Candy, it is possible that the daylily was stepped on and damaged at some point, causing the slow increase.
Anyway, in the last three years it has really taken off and is a nice clump now. Branching is at least 3-way, blooms always seem to open up beautifully, and the 26" registered height seems to be about what it is in my garden. I have not had rust on it either.
I have not noticed a fragrance, even though it is registered as very fragrant. I will have to try to notice that this year. It blooms between late June and mid-July here in my southern Indiana (zone 6b). Last year I had a few blooms in August, which were due to a little bud-building. But I do not get much rebloom here on any of my daylilies and have not had any on this daylily.
