Maurice - Thank you for taking the time to try to explain the "dormant" label on daylilies. I get what you are saying.
Then this leads me to another question ....
I KNOW I have dormants as described by the AHS. Almost always, after about 3 years, these plants disappear completely. I assume they just shrink little by little each year until they have decreased so much that they literally die. Is this typical of a true dormant daylily growing in central Florida climate or is something else possibly killing them? I have other daylilies growing near them and they don't die but continue to grow and bloom each year. The dormants will also bloom until they no longer come back. I wouldn't say they put on a great flush of blooms, but they do bloom. The returnee daylilies do not appear to be overwhelming the dormant plants into extinction from what I can tell.
This topic about dormants always has me confused because of what I am growing and observing in my garden beds.
