Soaptree yucca
Soaptree yuccas are natives of southwestern North America. Soapy material in the roots and trunks were used as soap. Its fibrous leaves were used for basket weaving.
Plants: These small trees are 4–15′ (1.2–4.5 m) tall, with a thick brown trunk, sometimes branched, mostly covered in a skirt of dried leaves.
Leaves: In dense whorls at the top(s) of the trunk(s). They are yellowish and leather-like, measuring 10–39 ⨉ ⅛–½″ (25–100 cm ⨉ 5–13 mm), with wiry white filaments.
Flowers: White, bell-shaped, about 1–2″ (3–6 cm) long. Flowers are on a spike that emerges well above the leaves.
Fruits: Capsules are 1½–3 ⨉ ¾–1½″ (4–8 ⨉ 2–4 cm).
Habitats: Dry, sandy plains, mesas and desert washes, desert grasslands.
