Identification: Plants reach 2′ (60 cm), or up to 7′ (2.1 m)
with the flower stalk. Leaves are 1-2′ (40-70 cm) long, wide at the base, narrowing toward the tips,
like large grass blades, with white twisted wiry filaments. They are bluish- to yellowish-green.
The flowering spike is covered with numerous greenish-white or purplish
urn-shaped hanging flowers, each with 3 petals. Seed capsules are dark brown.
