WILDFLOWERS OF NEW MEXICO

 

This widespread wild onion occurs throughout western and central New Mexico in arid desert and plains. Note the bracts around cluster or white, pink-striped flowers have 2–5 nerves, and each plant has 2 basal leaves that are longer than the flower stem (scape). Plants have 1–5 bulbs without basal bulbils (little bulbs) enclosed in a network of coarse fibers. Blooms in the spring.


FLOWER: March–June. A rounded cluster (umbel) with 10–20 small flowers blooms atop a 2–7 3/4-inch tall (5–20 cm) stem (scape); flowers bell-shaped (spreading open) to urn-shaped (constricted near top); 5/16–1/2-inch long (8–12 mm); 6 white to pink petals with reddish midstrip, tips pointed to rounded, stamens enclosed. Bracts around flower cluster have 2–5 nerves. Flowers do not form bulbils.


LEAVES: Basal, two per scape (flower stalk). Blades solid, channeled, 3–7 3/4-inches long (8–20 cm).


HABITAT: Sandy, gravelly soils; below pinyon-juniper woodlands in western and central NM deserts and plains.


ELEVATION: 4,400–7360 feet.
