Nolina nelsonii-Blue Nolina
This Nolina has
a bolder look than other Nolina species, and is often mistaken
for a Yucca species. The 2 to 3' long, 1'' wide leaves range
from grey-green and flexible (juvenile foliage) to powder blue
and less flexible (mature foliage). The leaves are edged with
tiny teeth that can inflict cuts on an unsuspecting gardener.
Blue Nolina grows at a moderate rate, eventually developing a 10
to 12' tall trunk, crowned by a 4 to 5' rosette of foliage. Old
leaves persist along the trunk, resulting in a naturally shaggy
look. These dead leaves can be removed for a neater appearance.
In the summer Blue Nolina sends up a 10' tall spike of small tan
flowers. Blue Nolina is very adaptable, tolerating full sun and
reflected heat, as well as part shade. Withholding irrigation in
the fall and winter will harden off Blue Nolina, and prevent
most frost damage. This native of Mexico is hardy to 10º F.
