Can people who grow this variety tell me if it needs to be in partial shade so that it doesn't melt? Thanks so much for your help!

I have trouble with anything in those shades, but my skies are cloudless with low humidity.

Ted Blaney is a talented hybridizer and a rigorous selector, so I doubt he would have introduced a daylily with unacceptable sunfastness.

"Daylily Math" doesn't really work, but here are some things to consider.

I've grown both of the parent plants for over 20 years, and they hold up well in the sun, so there's a good chance that Raspberry Suede will do fine in that regard.

Vintage Bordeaux has heavy substance and good sunfastness. Red Grace has normal substance, but it's "tough", in that the segments hold firm throughout the day. The color is a beautiful, clear, sparkling red in the morning, but it does dull some when the sun hits it. Both have intense green throats.

I'd say that it's well worth a try. Where did you find it listed?

Ken,thanks for taking the time to post an answer. I got Raspberry Suede from Parklane Daylilies in New York. Will you please explain what you mean mean by 'daylily math'?

It's just a sports expression I repurposed in order to imply that hybridizing is unpredictable, and that a good pedigree doesn't guarantee success.

Daylily Math, if it was actually valid, would work something like this;
Great Flower 1 x Great Flower 2 = Great Flower 3
