Ok, I know I want a long season of blooms, so I guess for me that is one of my first criteria for selecting my daylilies. But not just early or late, but how long of a period each one blooms, and the length of time between re-bloom must be taken into consideration. My, this can get complicated in a hurry!
Yes, strong scapes is a good trait to look for, don't recall that being a choice in the data base. But, I have some daylilies with weak scapes that will not hold the blooms up, and it is made worse because the plants are in the shade too much, must make a note to move those.
