Yucca queretaroensis - A single stemmed upright plant with heavy trunks to 12 feet tall with old leaves laying flat in a neat skirt. The tops of these trunks bear the bright green that are extremely narrow, less than 1/8 inch squared in cross section and 18-24 inch long that radiate outwards like a rounded head of hair. In habitat the flowers arise from amongst the leaves to 2 to 3 feet bearing white flowers but this plant has not be in cultivation long enough to know whether it will flower given garden conditions. This plant is considered by many to be THE most beautiful Yucca species. It was first described in 1989 in "Cactaceas y Suculentas Mexicanas" Vol. 34 (3) by Ignacio Piņa Lujan. It was described from plants from the Mexican state of Queretaro where it grows in small colonies on the steep slopes from 3,300 to 4,300 feet in the gorges along the Rio Extorax, a tributary of the Rio Moctezuma. It has since been also found in deep gorges northeast of Zimapan in the state of Hildalgo. This species belongs to the group of rupicolae that is most closely related to such familiar species as Yucca rostrata, Yucca glauca, Yucca rigida and the similar looking Yucca thompsoniana, which has wider flat leaves and Yucca linearifolia from which it primarily differs in having a heavier trunk and square leaves in cross section (Y. linearifolia are about as wide but flat). We are fortunate to have seen Yucca queretaroensis in its native habitat in Queretaro and noted a fine large specimen in the Mexico City Botanic Garden.
The description above is based on our research and observations of this plant growing in our nursery, in our own garden and in other gardens in the Santa Barbara area. We would appreciate hearing from anyone who has additional information about this plant, even if they disagree with what we have written.
