This obligate mutualism is similar to that of yuccas and yucca moths. Yucca is a genus in the plant family Asparagaceae containing species commonly known as yuccas. Hikers often encounter Parry's agave, yuccas, and prickly pear cacti in this region as well. Flora include willows, oleanders, Russian olives, yuccas, palms, and pines trees. Another well-known example of plant-organism interaction occurs between yuccas and yucca moths. The cemetery contains over 600 gravestones, several yuccas, a hemlock tree, and a boxwood. These areas include pinyon and juniper trees, sagebrush, yuccas, cacti, and creosote bushes. Some yuccas store water in thick, fleshy leaves. Yuccas and cacti can be found at the south end of the property. An oleander at the rear and three yuccas near the gate add the old-time touch. Yuccas are widely grown as ornamental plants in gardens. Yuccas have adapted to an equally vast range of climatic and ecological conditions. Yuccas are widely grown as architectural plants providing a dramatic accent to landscape design.
