The "plantlets" on the daylily bloom scapes are called proliferations. You can cut the scape above and below them, take that middle piece - with baby roots - plant it in the ground, and it will become a new plant. Just - as always - be careful to not plant the crown more than an inch below ground. (Some daylilies have this proliferation trait, some do not. Some people value this trait - MORE PLANTS! - but I think it just looks messy.)
As for daylily bloom colors, those are affected greatly by climate and soil conditions. I have noticed quite a difference in bloom color saturation in my garden, when there is a rare humid day in the bloom season (which peaks hereabouts around June 10th). The colors are so much better - glowing, almost. Also, cool nights (particularly at the beginning (early May or earlier here) and end (October-November, for rebloom) of the daylily bloom season) will adversely affect surface color formation, as well as such traits as "sharks's teeth".
Howard Hite was a daylily person with a commercial garden, which is how I got 'White Stripe' from him. I think that he introduced 'White Stripe', but that it may have originated with someone called Mullison. (The AHS registration data says "Mullison-Hite".)

Thanks to all for their comments on
I. pallida performance. I may still get one plant (where can I shoehorn it in?
with lavender flowers, not the Moon Garden) because I am curious about the "grape soda" fragrance (and if it would be possible to get a white flowered variegated seedling from it).
