Abstract
Daylilies (Hemerocallis species and cultivars) are herbaceous perennials much sought after for their showy albeit very short-lived blooms. The mature plant is comprised of fans (ramets) consisting of an underground stem (rhizome), an expansive fibrous or fibrous-tuberous root system, and strap-shaped leaves. Axillary buds can be forced to yield vegetative separations. The deciduous or evergreen foliage consists of sheathed-at-the-base, heavily ribbed leaves which when mature (Fitter and Krikorian 1985; Smith et al. 1989) are long and two- ranked. Flowers are borne on a scape, often branched and largely leafless but with bracts, and shoot propagules (“proliferations”). Flower buds per scape may vary from around 5 to 20 (Wilkins 1985).
