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!.
