I acquired this as a Butia x cocos hybrid. It was hybridized from a very knowledgeable Butia x Syagrus hybridizer. This is 1 of only a handful that survived. It is still small (7 gal), & I am waiting to see how it ends up looking. It is definitely different from the standard Mule, in that it went pinnate while still small & immature. The few others that have survived in FL are larger because they were bumped up to 7 gal sooner & were grown in more Sun.
