Truly an incredible variety! The color and size of the flowers is unbelievably stunning, and this one really will call to you across a great distance. If you're looking for a bright, eye-catching yellow daylily, this is definitely the right choice! I grow a great many daylilies, but this one has become one of my all-time favorites, and certainly my favorite yellow. Even my non-gardening friends are struck by the intense color!

Mary's Gold called to me in a display garden with hundreds of daylilies blooming. The huge bright flowers are a knockout! You must see her to appreciate her.
