Asphodelus fistulosus is a species of plant known as hollow-stemmed asphodel,[2] onionweed,[3] onion-leafed asphodel, and pink asphodel. It is native to the Mediterranean region as well as the Arabian Peninsula, Transcaucasus, and Madeira.[4]
It is an invasive exotic weed in the United States, with significant infestations in California, Arizona, New Mexico, and Texas. It is listed as a Federal Noxious Weed by the United States Department of Agriculture. It is also a common weed in parts of Australia, New Zealand, and Mexico, and it thrives in any area with a Mediterranean climate.
It is an annual or short-lived perennial herb growing a hollow stem up to 70 centimeters (28 in) tall. The root system has a series of tuber-like parts at the base of the stem. The plant takes the form of a large tuft of onion-like rounded hollow leaves up to 30 centimeters (12 in) long. The inflorescence is a panicle with widely spaced flowers. Each flower is 5 to 12 millimeters wide with six tepals which are generally white or very pale pink with a neat central longitudinal stripe of brown to reddish-purple. The flowers are diurnal, closing at night and in overcast or low-light weather conditions. The fruit is a rounded capsule containing six seeds.
Two subspecies are accepted.[4]
- Asphodelus fistulosus subsp. fistulosus – Mediterranean basin, Arabian Peninsula, and Transcaucasus
- Asphodelus fistulosus subsp. madeirensis Simon – Madeira
