Yucca Filamentosa/Yucca Glauca and winter
Wondering if anyone grows Yucca Filamentosa and if so, how does it fare for you?
Does your yucca suffer winter damage? Most sources state it is hardy to zone 4 and I have found how well it survives winter here depends on the year. I have concluded that the roots are definitely hardy, it's the evergreen leaves that suffer winter damage.
Most years mine suffers moderate damage, but recovers nicely. One year I thought it was totally dead, but it did come back, another year it had little winter damage and even bloomed one summer.
I have ordered Yucca Filementosa 'Color Guard' from a catalogue. The catalogue states it's hardy to zone 5, but I am hoping it might be at least as hardy as the regular green one I have.
Does anyone winter protect their yuccas? Is the damage to the leaves over winter caused by winter desication from the sun, similar to conifers, and would "wrapping" them help? I have already piled a mound of snow over my green yucca.
I also have the hardier yucca glauca but while it is unique looking, the leaves seem more curly/wavy and rest on the ground. Only recently has it begun to develop leaves that are more straight and upright (it is in full sun).
