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.

Yucca pallida ( Catalan; Valencian )

provided by wikipedia CA

La Yucca pallida és una planta del gènere Yucca, de la família de les agavàcies.

Distribució

Es troba al nord i centre de Texas, i a l'extrem nord de Mèxic. Destaquen les seves fulles pàl·lides, amb tonalitats que van del blau grisós pàl·lid al verd apagat.

Descripció

La seva altura arriba a 20-50 cm i 30-80 cm de diàmetre, amb fulles de 15-40 cm x 2-3 cm (són més amples pel mig). Les rosetes es recolzen directament al terreny amb poc o cap tronc. Les fulles tenen espines terminals amb colors de groc a castany i són, generalment aplatades, amb una mica de cera a les vores.

La inflorescència és en panícules d'1-2,5 m d'altura, amb més de 100 flors acampanades, cadascuna de 5-7 cm de llarg, amb coloració que oscil·la entre el verd suau a crema.

Se sap que hibrida amb la Yucca rupicola, d'aparença similar, amb fulles més retorçades i corvades.

Encara que no és una planta molt comuna en horticultura, el seu color, mida i moderada resistència (aguanta temperatures de fins a −18 °C) la fan una bona alternativa per a altres tipus de iuca.

Yucca pallida ( German )

provided by wikipedia DE

Yucca pallida (englischer Trivialname: Pale Leaf-Yucca) ist eine Pflanzenart der Gattung der Palmlilien (Yucca) in der Familie der Spargelgewächse (Asparagaceae).

Beschreibung

Yucca pallida wächst solitär und stammlos oder bildet kleine Gruppen. Die variablen blauen bis graugrünen Laubblätter sind 20 bis 35 cm lang, 1 bis 1,5 cm und an der Basis bis 3 cm breit. Sie sind wie alle Vertreter der Sektion Chaenocarpa Serie Rupicolae an den Blatträndern fein gezahnt.

Der über den Blättern beginnende, verzweigte Blütenstand wird 1 bis 3 Meter hoch. Die hängenden, glockigen, weißen bis cremefarbenen Blüten weisen eine Länge von 5 bis 6,5 cm und einen Durchmesser von 2 bis 3,5 cm auf. Die Blütezeit reicht von April bis Juni.

Vorkommen und Systematik

Yucca pallida ist verwandt mit Yucca rupicola, einem weiteren Vertreter der Sektion Chaenocarpa Serie Rupicolae. Jedoch ist sie deutlich zu unterscheiden durch die einmaligen, gedrehten Blätter.

Yucca pallida ist in Mitteleuropa, Deutschland, Mannheim frosthart bis −20 °C. Erstaunlicherweise ist sie eine der härtesten Yuccas in Mitteleuropa, obwohl in dem Verbreitungsgebiet in Texas kaum Frost vorkommt. Ohne jeden Schutz wird diese Art in der Sammlung von F. Hochstätter seit fast 20 Jahren kultiviert. Sie ist in den Sammlungen jedoch selten.

Der botanische Name pallida bezieht sich auf die eher blasse Färbung der Blätter.

Yucca pallida ist in der „Blackland-Prärie“ in Texas in kalkhaltigen, steinigen Böden und in Grasland in Höhenlagen zwischen 200 und 300 m verbreitet. Diese Art wächst oft vergesellschaftet mit verschiedenen Kakteen-Arten.

Die Erstbeschreibung durch Susan Adams McKelvey unter dem Namen Yucca pallida ist 1947 veröffentlicht worden.[1]

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.
