Yucca pallida McKelvey

Comments

provided by eFloras
Yucca pallida is endemic to the blackland prairies of Texas and was originally included in Y. rupicola. J. M. Webber (1953) indicated that he found plants of Y. rupicola with key features similar to those of Y. pallida. Occasionally, plants with entire margins are found; these have been called Y. pallida var. edentata, which S. D. McKelvey (1938–1947) suggested might be a hybrid between Y. pallida and Y. arkansana. K. H. Clary (1997) indicated that DNA evidence confirms the close relationship of Y. pallida and Y. rupicola.

Leaf blade lanceolate, straight, flat except becoming concave near apex, widest above middle, 20–50 × 1–4.5 cm, flexible, glaucous, margins denticulate or sometimes wavy, yellow. Inflorescences paniculate, often distally racemose, arising beyond rosettes, 7–12 dm, with wide-spreading branchlets 1.5–2.3 dm; bracts erect; peduncle scapelike, 0.6–1.3 m, less than 2.5 cm diam., glaucous. Flowers pendent; perianth campanulate; tepals distinct, greenish white, elliptic to ovate, 5–6.5 × 2–3.2 cm; filaments 1.8–3.2 cm; pistil 3.2–4 cm; style white, 13–20 mm; stigmas lobed.

Yucca pallida

provided by wikipedia EN

Yucca pallida, sometimes called pale yucca, is a species of yucca native to Northern Mexico and parts of the blackland prairies of northern and central Texas, and notable for its light-colored leaves that range from a pale blue-gray to sage-green in color.[3]

The rosettes average 20–50 cm tall and 30–80 cm in diameter, with leaves 15–40 cm long and 2–3 cm wide, being widest around the midpoint. The rosettes sit directly on the ground, with little or no trunk. The leaves have a yellow to brown terminal spine, and are generally flat, possibly with some waviness or rolling along the edges. The inflorescence is a panicle, 1–2.5 m tall, with up to 100 bell-shaped flowers, each 5–7 cm long, with color ranging from light green to cream.[3]

Yucca pallida is known to hybridize with Yucca rupicola Scheele, which has a similar appearance, but whose leaves are more twisted and curved.

Although not common in horticulture, its color, size, and moderate hardiness (down to −18 °C or 0 °F) make it a good gardening alternative to other species of yuccas.
