Great Yucca ! It's a really cold hardy plant. Survived in our garden the last winter 2008/2009 with 8weeks permafrost down to - 5 F during the nights without damage !!
Our faxoniana is 90 inch tall.

Very beautiful plant. Grows everywhere in the Denver metro area. In a lot of people's yards.

Relatively large, long, flat, straight, sharp pointed leaves on a woody stem. Plant is a Texas native around the Big Bend area, but also occurs in N Mexico. Usually sold in nurseries under the synonym Yucca carnerosana. But not a common find at most nurseries... a bit costly and large plants are very costly. A wonderful specimen plant for the right desert garden, particularly if trimmed up well.

Seems odd it would be growing in Denver, a climate which often sees temps far below 10F, which is the minimum temperature of this species.


This plant has been said to grow in the following regions:

Orange Beach, Alabama
Phoenix, Arizona
San Leandro, California
Boulder, Colorado
