Hardiness:
Not known, Yucca baileyi is probably quite hardy, but will probably need to be protected against winter moisture. If the plants that are cultivated in Hungary is true Yucca baileyi it may be very hardy. When my plants are older and have been tested outside will I report back on this page.

Pictures:
Below is are 2 pictures of cultivated plants in Hungary, note that the last has seed pods, very unusual in Europe!.
