More Information About Butyagrus
x Butyagrus is a naturally occurring inter-generic hybrid cross between Butia capitata (Jelly Palm, Pindo Palm) and Syagrus romanzoffiana (Queen Palm) that occurs where their territories overlap in Uruguay and Argentina. The offspring of this cross ex hibit hybrid vigor and grow rapidly up to their 18' max imum height. However, like their common name implies, mule palms are sterile. x Butyagrus plants sold in the horticultural trade are not collected from the wild but are instead generated at nurseries by horticulturists who make painstaking manual crosses of the two parent species.
The first horticulturist to make this cross and artificially create x Butyagrus was the French nurseryman Paul Nabonnand for whom the epithet nabonnandii was coined. Monsieur Nabonnand was a palm ex pert whose main goal was to find a cold hardy palm tree that would produce date fruits. He failed in this attempt but did create a beautiful ornamental palm in the process. x Butyagrus is not one of the most cold hardy palms for sale, but it is still an ex cellent ornamental palm tree where it can be grown.
Like its butia parent, x Butyagrus is a cold hardy palm tree and can be grown in the southeast US in zones 8b and warmer. As they grow larger, the plants become more cold tolerant, so if you buy a small x Butyagrus, you should grow it in a container for a few years before planting it outside. x Butyagrus is a very attractive palm with a lush feather palm appearance. x Butyagrus plants are adaptible and tolerate full sun or part-shade, drought, clay or sandy soils, and salty water from coastal environments. x Butyagrus prefers well-drained soil, especially during the winter, to prevent rot.
In the trade, this species has a few different names. You may occasionally see it sold as Syagrus x fairchildianae or x Butiarecastrum nabonnandii. You may also see the name spelled as either x Butyagrus or x Butiagrus. Although it would seem that since Butia is the parent, that x Butiagrus would be correct, the proper spelling is x Butyagrus as it takes the "But" from Butia and the "yagrus" from Syagrus.
