## Family Asphodelaceae

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

### Submily Hemerocallidoideae
#### Tribe Hemerocallideae
##### Hemerocallis

* Hemerocallis fulva orange daylilyAlthough 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.
