Sometimes called Beaked Yucca, Big Bend Yucca, Silver Yucca and Nordstrum's Yucca, Rostrata is a hardy evergreen, trunk-growing tree-like yucca that will take the dryness, the heat, the winter, the rocky soil and the occasional summer downpour. They establish themselves quickly and look spectacular reflecting light from the desert sun. Over its life span, the Rostrata can reach fifteen feet with multiple three foot wide, silver-green heads. The dead leaves remain on the plant, sheltering the trunk as it grows. The clustered white flowers, too, are stunning, emerging in late spring and early summer, reaching up to the sky on tall stems.
Rostrata roots very easily. Water regularly until established. This will help the plant extend roots deep enough to help it resist strong winds. Once established, watering should be very light. Feed the plant with an organic general purpose fertilizer in the spring.
This plant was utilized extensively by native cultures; the flowers for food, the spines for many uses including baskets, clothing and soap. The flower pedals are said to be quite tasty if harvested at the right time and great in salads. The fruit, if allowed to mature, can be used to make soups and other interesting dishes.
This spring Drycreek has a new crop of Rostrata in several sizes, as well as many other types of hardy Yucca.
