Abstract
A new variety of daylily distinguished by its clear, unspotted, lemon-yellow color, and particularly characterized by its consistent ability to increase eight to twelve times per month under tissue culture laboratory propagation procedures, a character that is very uncommon for daylily propagation on a commercial scale. This new daylily cultivar has the further advantages of a very hardy growth habit when grown in the northern United States climate zones and it withstands very well the cold winter seasons.
