Short description of the species:
Acaulescent or with prostate short stem (30-60 cm) the plants can be
huge clumps up to almost 300 cm in diameter, such a large plant may have
10 or more rosettes of leaves; Leaves narrow linear, 55 to 70 cm
long, 7 to 13 mm wide, grayish or glaucous green, with a narrow white edge,
with few fibers (some forms has many fibers along the edge!) Flowers
pendulous (bell shaped) greenish white, 6 to 7 cm long in large branched
100 to 180 cm tall panicle, the lower branches are 15 to 20 cm long those

more than 12 mm long.
Hardiness:
Here in Northern Denmark Yucca glauca ssp. stricta is
quite hardy, but after a very wet winter some of my plants did root in
the center, but will recover from the rhizome. None of my plants has bloomed
yet, but maybe this year?
