[9] It persists also where dumped and spreads more or less rapidly by vegetative increase into woods and fields and along roadsides and ditches, hence its common name ditch lily.
Over the next hundred years, thousands of different hybrids were developed from only a few wild varieties. In fact, most modern hybrids are descended from two types of daylily.

The starting-points for List of elm cultivars, hybrids and hybrid cultivars were fourfold: (1) Green's 'Registration of Cultivar Names in Ulmus ' (1964), [1] based on the contemporary nomenclature of elm species and wild hybrids; (2) Krüssmann's confirmation or correction of cultivar-names in his monumental Handbuch der Laubgehölze (1976); [2] (3) Heybroek's table of Netherlands research ...

The IUCN also lists 244 subspecies and 235 varieties as Vulnerable. No subpopulations of plants have been evaluated by the IUCN. For a species to be assessed as vulnerable to extinction the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild".
