yucca glauca

Yucca glauca is the most common native yucca in my area of town, growing naturally in the grassland areas. Other yuccas, Yucca thompsoniana, Yucca rostrata, Yucca baccata and Yucca elata, are planted commonly, but of these, Yucca baccata (the banana yucca) is the only one that is locally native, growing naturally on the hillsides. They bloom at various times, each species on its own time schedule. I'm fascinated that they are pollinated by a moth whose larvae eat the developing seeds (and leaving many more to grow).
