Gardeners' Notes:

This is a really pretty pale yellow that reblooms like Stella d'Oro but it is a softer color that goes with everything. The flowers are also bigger. It is hard to go wrong with this one.

Love the color, love the fragrance, love the overall look of the plant. Very healthy and long-blooming. I'm not a huge daylily fan, but this one has earned a place in my perennial beds. Stays in a nice clump--does not spread all over!
