Yes, daylillies are edible, and the buds are used in salads some places. I've tried some of mine, and not been thrilled. I'd bet that because all we select for in the USA at least is color and form, taste will vary, and selected varieties might be delicious, or not.

I had probably 50 different varieties, chosen for flower color, type, etc., and only sampled one or two - wasn't overwhelmed with joy about the taste and never ventured any further...I just loved how easy they were to grow and the lovely variety of flowers and colors.
