Patrix hybrid cold hardiness

[Fallen Munk]

It's been a colder winter than average here in the PNW with many frosty nights.  I appears that the Jubaea x Butia yatay is more cold hardy than the Butia yatay x Jubaea.  The BY X J is showing quite a bit of tip burn, while the J X BY is totally fine.

Just my personal observation.

Butia yatay X Jubaea (note tip burn):

Jubaea X Butia yatay:

Here is my Butia x Jubea which saw our Christmas freeze (10.6F low with frost cloth) and many other cold nights.. I threw a cloth over it when it was raining ice but nothing much of anything else... it looks beautiful!

Just want to reiterate that even among the same cross hardiness will be variable. With F1’s just a lot of variables even more so with a triple cross.

We had a low of 11f here in Raleigh during the polar express. During that, I covered my PS butia yaytay x jubaea with a black bucket. That was our lowest temp this winter by far. We've had no frozen precipitation either. The palm has looked great up until this past week when the fronds started to brown. I tugged at the spear and it came right out. I treated it with copper fungicide but I'll have to wait and see if it survives. If it doesn't, I'm giving up on the hybrids.

wow that is disappointing..... I had some basic C9 Christmas lights just put on the petioles closest to the trunk with a frost cloth but that is it.  I have a rescue butia that is across the yard, no supplemental heat, it spear pulled (two years in a row) and it's about to push that spear right back out.  I only have these three that I will protect long term and 150+ sabals with zero protection so it makes this much more doable.  I have heard the Jubea x Butia is much hardier, both leaf hardy and spear hardy.  FWIW my Butia x Jubea did NOT come from Patric but from Moultrie Farms (now that I think of it)..

It seems to handle this a bit better.  It has pushed probably 8" since the Christmas freeze so I know it's doing just fine and I've tried giving the spear a tug.  Sorry to hear that

My yata x jubaea (5gal) growing in ground 1.5yrs spear pulled as well. I cut it back to prevent rot, treated with copper fungicide and it’s pushed several inches of new growth in 3 weeks time.
