What's faster: Mule Palm or Butia x Parajubaea?

[Sandy Loam]

Which is faster growing, at least in Florida?:

Butia Odorata x Parajubaea Cocoides (hybrid)

OR

Butia Odorata x Syagrus Romanzoffiana (hybrid - "mule palm" )

I already have a mule plan and am considering purchasing a BxPJ as well.  There are reports that they grow quickly in California, but I just don't know about Florida. Parajubaeas sometimes don't like our humidity and wet weather in Florida (the current drought is abnormal).

Also, what is the cold tolerance of Butia x Parajubaea Cocoides relative to a typical Mule Palm?

Finally, is Patric Schaeffer still the only person on the planet selling Butia x Parajubaea hybrids?

And my very last question -- Has anyone heard of pathogens like Fusarium Wilt attacking the Mule Palm due to its syagrus lineage?

Mule palm grows faster for me.

[Ben in Norcal]

Wow.  I can't speak to other climates, but BxP easily 2-3x faster for me here in California.  No comparison.

[Darold Petty]

Yah, what Ben said,  we have a Patric BxP at the Lakeside Palmetum in Oakland.  It is easily the fastest growing palm in that garden.

Off topic: Are BxP sterile like BxS?  What BxP flowering history is known at all?  Pardon the threadjacking.

[TexasColdHardyPalms]

Good question. I thought there was a pic of an older hybrid in another thread. The owner may be able to answer.

[Ben in Norcal]

I don't think BxS are sterile - they are just self-sterile.  Right?

[TexasColdHardyPalms]

I believe the male pollen is sterile, but the female flowers are receptive.  I dont have large enough specimens to know for sure.

I have a cross that Patric S. did that is half mule, so I think somehow it is possible...

Has anyone heard of a mule palm being killed by the pathogen which is now killing so many Washingtonias, Syagrus and Phoenix palm? (At least in Florida)  If this were a possibility, I would err on the side of the Butia x Parajubaea hybrid instead of planting another mule palm.  I just don't know whether the Butia "half" of a mule makes the whole tree less susceptible to syagrus diseases.
