Iris subg. Limniris

Iris versicolor

Iris subg. Limniris sect. Limniris includes irises often referred to as flags, the most common of which is the northern blue flag (Iris versicolor), which grows in a wide range of wetland types.

Iris versicolor has been shown to be an amphidiploid between Iris virginica (n=35) and Iris hookeri (n=19).^[1]

Crocus tommasinianus

The only vouchered Crocus specimen listed from New York State is of Crocus tommasinianus, which is listed as not naturalized in the New York Flora Atlas. However, several other Crocus species have appeared on the checklist of New York State plants, ^[1] but these are now listed as "excluded" in the Flora Atlas.

Family Asphodelaceae

The Asphodelaceae (or Hemerocallidaceae^[1]) family contains the non-native orange and yellow daylilies.

Submily Hemerocallidoideae

Tribe Hemerocallideae

Hemerocallis

Hemerocallis fulva
orange daylily

Although the common form of the orange daylily Hemerocallis fulva is a seedless triploid and essentially sterile, it has persisted after, and escaped from cultivation so successfully using vegetative means such as root fragments, that it is considered invasive in much of the world, including New York. By contrast, the fertile diploid yellow daylily, Hemerocallis lilioasphodelus, though reportedly naturalized in some places, is not currently considered invasive.
