So often we think we know all about a plant, when we’ve only grown a single clone, and we all know what happens when we assume! A good example is the Southwest US native Agave parryi ssp. truncata, which is now grown around the world. 99.9% if the plants in commerce are a single clone, know as the Huntington form. Unfortunately, this clone is not reliably winter hardy north of Zone 8b.
Many years ago, we received a new clone via the late nurseryman, George Hull. Having survived for us without damage since 2010, including two winters of single digit F temperatures, we have christened this Agave parryi ssp. truncata ‘Hardy Boyz’. Below is a photo taken last week. It’s been very slow to offset, but we feel this an exceptional clone worthy of propagation and distribution. Stay tuned.
Interesting. Thanks for the post. What zone is Raleigh?
