Yuccas have a very specialized, mutualistic pollination system; being pollinated by yucca moths (family Prodoxidae); the insect transfers the pollen from the stamens of one plant to the stigma of another, and at the same time lays an egg in the flower; the moth larva then feeds on some of the developing seeds, always leaving enough seed to perpetuate the species. Garland Gold has leaves with a gold center stripe. According to eHow, the many species of yucca have adapted in slightly different ways, but they are similar in one respect: they all depend on a specific genus of moth for pollination. The root system is well adapted to water storage, quickly consuming the rainfall that the leaf structure directs toward the center of the whorl. Think of the wackiest adaptations possible (such as umbrella-shaped leaves for shade). It is possible that Bright Edge, and Colour Guard, listed above, are members of this species rather than Y. filamentosa.
