Parajubaea Hybrids Observation

[NWpalms@206]

Hi folks, just wanted to share something Noteable with my Parajubaea hybrids (Patrick). Specifically BxPJT and BxPJS, both strap leaf just going pinnate. I am PNW Vashon Island WA 8b/9a. So both of these were left outside under no cover until December, they experienced one good frost, and then put in unheated greenhouse. They were in the greenhouse during the cold snap here in Seattle area end of Dec, and got down to 20f maybe 19. Last week I noticed some white mold on both my BxPJT so I treated and brought the smaller one inside along with its counterpart BxPJS as mentioned above. I did not find any fungus on any PJS hybrids (7) but both PJT. As of now the smaller BxPJT has double pulled and is molding over, the BxPJS has NO mold and as you can see by marker it’s growing now. The larger BxPJT has shaken the mold and seems ok for now. But anyways from what I’m seeing PJS does have better wet and fungus resistance. Also my larger BxPJS doesn’t show the yellowing or spotting of some of my other Butia hybrids (especially mule). Just wanted to add to the knowledge pool something maybe to think about if considering these two. Happy growing!

Thanks for sharing.  I picked the BY x PJS over PJT for these exact reasons, or at least my suspicions that they would deal with damp conditions better.  This makes me feel like I made the right choice, now whether or not they will be hardy in ground, only time will tell.  My two are doing well and have been pinnate a while, but so far have lived indoors.

Very keen to see how these do for you both once they are in the ground. Good to know that the PJS seems superior to the PJY so far. I’m sure these will be beautiful, stately palms that will look totally out of place (in a good way!) in the PNW. I’ll have to source one or two from somewhere if they work out well for you.

Yeah I had heard some speculation based on the Sunkhas natural habitat and elevation. And the fact that Torallyi is known to be temperamental and outright die sometimes. But there’s just such limited data on these newer hybrids especially in our climate. Not many folks experimenting with this stuff up here, although some.

Im excited and nervous to plant out my big BxPJS. I anticipate some protection for the worst of its first few winters… but with a prime location, some luck, and natures blessing it will grow many years. I’ll keep updates and if you want one Talk to patrick!

I have a few pure Parajubaea torallyi (var. microcarpa) that I germinated from seed doing fine in the PNW zone 8b.  Still in strap leaf though.  Was tempted to order some hybrids last summer but got vetoed by my wife.

I planted this parajubaea torallyi a year ago and it has been doing pretty good I think. We have had several nights with frost and temperatures down to 27F.  Last three nights in the 27-29F range and no ill affects.

Here is the same palm ten months ago.

Loaded wrong photo on last post, sorry.

I got the olive shaped seeds on the right from a Parajubaea Coccoides and the seeds on the left from the Parajubaea palms at Ventura College. I was wondering if the seeds on the left might be Torallyi ?

For what it's worth, my larger Butia odorata x Parajubaea torralyi came through the freeze well, but I did protect it. I have not planted out my B. x Parajubaea sunkha yet, but will this spring. I estimate both saw ~24 degrees but many frosts beforehand. They are larger plants however, with the B x PJT having been in ground a few years now.

All my Patric hybrids have performed extremely well for a dry cold snap. With no supplemental heat and there first winter I'm really impressed. Even the fronds that peaked out of protection weren't harmed 😃 17° F
