YUCCA GLORIOSA FLOWERING

Ann Richards2

 

I think this plant is a Yucca Gloriosa (?). It normally buds in September and flowers fully in November (approx 6 weeks) but this year one spike flowered normally but then two more spikes grew to full height with all their buds on but it still hasn't flowered and the weather is above to nosedive.  These are well established plants and look quite tough as they have a thick fibrous covering, even on the buds.  Do you think they will still flower soon, wait until the Spring or die in the bad weather please
