I purchased Little Grapette at one of the big box stores (Home Depot or Lowe's, I forget which). It was one of the first three daylilies in my garden. Since I purchased it, it has multiplied well. It's color can vary slightly, but it generally has good, consistent color and form. I like that it's eye isn't too prominent, too, it blends in well with the rest of the flower.
As far as hybridizing goes, Little Grapette is both pod and pollen fertile, but not to any noteworthy extent either way. I should note, however, that I rarely use it as a pollen parent. Since I'm somewhat new to hybridizing and don't have any blooming child plants from it yet, I haven't formulated an opinion of its offspring. I did, however, get a seedling from it (it was either "Pardon Me x Little Grapette" or "Little Grapette x Pardon Me") that appeared to not have the ability to produce chloraphyll; it grew out with white leaves and died off within a few weeks. Whether this is a random mutation possible from any combination of daylilies or whether Little Grapette may somehow be responsible for an increased likelihood of this genetic abnormality, I couldn't say.
Overall, Little Grapette is a cute little daylily. It isn't one of my top favorites and I wouldn't go out of my way to recommend it to anyone, but it's earning its keep in my garden well enough for now and it is one of my shorter daylilies, so I keep it to hybridize for shorties.
