A professor of biological sciences at DePaul University for 34 years, Dr. Griesbach developed a new method for doubling the chromosomes in Daylilies. With four sets of chromosomes, tetraploids offer more color possibilities, increased vigor and substance, and larger flowers. We are honored to offer a selection of his outstanding Daylilies.
Daylilies bloom in summer and are very long lived, easy to grow perennials. We ship double-fan, bare root Daylilies from mid April through November, weather permitting.
Our Daylilies are hardy, dormant-type varieties grown in our fields in southern Wisconsin. Recommended for USDA Hardiness Zones 3-10.
