I have never removed scapes on new acquisitions. One reason is that I want to know that what was ordered is the same as what I received. Another is I'm impatient to see those blooms anyway; I like the grassy/clumpy look of daylilies but I'd probably go with some type of grass if that was all I wanted. So I just let the plant do its thing. I figure if it can't handle producing a scape, it will abort it - and I've had that happen a couple of times when scapes showed up on new acquisitions. Since the plants have gone on to increase well, I haven't thought it hurt the plant to allow the bloom.
