Iris subg. PardanthopsisEdit

Iris domestica

Iris subgenus Pardanthopsis contains the two species Iris dichotoma and Iris domestica.

Despite possessing a "very un-Iris-like flower," ^[1] the sole species of Belamcanda has recently been transferred to the genus Iris, as Iris domestica. ^[2]

CrocusEdit

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 AsphodelaceaeEdit

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

Submily HemerocallidoideaeEdit

Tribe HemerocallideaeEdit

HemerocallisEdit

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.
