dry winters equal less frost damage to cacti and suculents..usda hardiness zones are flawed and always will be.my microclimate is at least a zone 7.the weather records that are available online are irrelevant because the offical records are taken at the airport, 15 mile from here!. I've lived in the same place for 20 years.one bad below zero spell in that time, and more days above 100 than any big place in colorado

Near the west fence on the north side of my driveway I have a healthy, but older, Spanish dagger yucca cactus. It bloomed last year with a white flower display. This Spring, I have three (3) pups developing on the trunk of this cactus. I am most interested in harvesting those pups and propagating this cactus in my cactus/desert landscape. Questions:
1. Should I expect my original yucca to die now that it has bloomed and produced pups?
2. Do I just take my machete and whack off the pups?
3. Should the pups be allowed to dry for a few days or for a week before planting?
4. Do I need to place the pups into a container and allow them to show growth and accommodation before setting them in the cactus bed?
5. Can Spanish dagger yucca cactus be planted i... read more

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.

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.
