What’s the latest point you’ve had them bloom?
It kinda depends on the year and the weather and the individual variety. I want to say October is not too unusual. The hotter and dryer the year the sooner they stop blooming.
Thanks.
John this needs a drawing explaining what you say : the mechanism of transmitting of the features of the hemerocallis.

Michel – I wish I could explain the mechanism. The genetics of daylilies are complex enough that they have not been sorted out yet. There has not been a mapping of the genome like has been done for some commercial crops. So it is simply trial and error choosing parents with desirable traits and waiting to see the results two and three years later. I know from personal experience that crossing a very short plant with a very tall plant can give mixed results both short and tall. Similar results crossing one color of flower with another. It is often a surprising journey. And fun. Thanks
